GE IS215AEPAH1A Fan Control Card Printed Circuit Boards

The IS215AEPAH1A AEPA card module assembly is manufactured by GE Energy for use with the Mark VIe wind turbine control system family.

Product Description.

This IS215AEPAH1A printed circuit board was originally designed for General Electric’s Mark VIe series.

This Mark VIe series is a line of wind turbine system control and system control component products.

These products are actually manufactured by GE Energy, an alternative energy manufacturing company that exists as a shell company for retailers of the General Electric industrial giant.

This is a revised printed circuit board, modified from its original IS215AEPAH1 parent board by including a single-function revision rated “A”.

This GE Energy Mark VIe Wind Turbine www.ge-drive.com Series PCB can be more accurately defined as an alternative energy power assembly by its functional description.

Hardware Tips and Specifications

This IS215AEPAH1A Alternative Energy Power Assembly may be best understood when its hardware elements are contextualized according to the intended function of this printed circuit board.

The first descriptor for the function of this AEPA-abbreviated product is present in its functional description as an alternative energy power supply assembly.

This functional description happens to be an exact match to the AEPA functional acronym for this product, a rare blessing for a specialized Mark VIe series product.

The series to which this IS215AEPAH1A board belongs actually provides additional insight into the functionality of this product.

Considering the place of the IS215AEPAH1A PCB in the Mark VIe family of wind turbine control systems, it is not surprising that this GE Energy board is dedicated to wind turbine applications.

Now that the functional status of this IS215AEPAH1A PCB as an alternative energy power supply assembly has been described.

Then it is possible to highlight some of the hardware specifications available for this Mark VIe wind turbine series product.

Considering this product’s place in the specialized and recently developed Mark VIe wind turbine family, little original product-specific instruction manual material detailing the hardware of this IS215AEPAH1A PCB exists online.

That said, this initial Mark VIe series label identifies the board as an alternative energy power supply assembly with special component versions.

This IS215 series label has dual naming capabilities for this IS215AEPAH1A product; it also outlines its status as a domestic GE printed circuit board.

The original manufacturing location of this PCB can be traced more specifically to GE’s plant location in Salem, Virginia.

In this IS215AEPAH1A part number, the IS215 series label is followed by an example of the AEPA functional acronym.

It is itself followed by the H1 series grouping label, which, like the IS215 series label mentioned earlier, provides a dual naming convention for this product.

This H1 grouping label indicates that the product is a conformal coated printed circuit board with Mark VIe series grouping.

While the conformal style of PCB coating specific to this power supply assembly is well documented, given its widespread use on General Electric circuit boards, the first Mark VIe grouping of this part is the Mark VIe grouping.

The true meaning of the first set of Mark VIe series alignments for this component has been lost.

The last A digit of the IS215AEPAH1A part number is a reference to a Class A functional revision of this part, which may significantly affect the performance specifications and original measured dimensions of this IS215AEPAH1A product.

SBS IP-Quadrature Quadrature Decoder IndustryPack Module

Product Description

IP-Quadrature provides high density, cost-effective flexible implementation of four quadrature decoder channels. Channels may also be used as general purpose counters. Four independent channels provide 24-bit resolution, programmable modes, programmable polarity, interrupt capability, differential or single-ended (RS-422 or TTL/CMOS) input, read-on-the-fly capability, and a count frequency of 0 to 10 MHz.

Quadrature encoders are popular sensors that provide accurate, low cost incremental motion sensing. Most commonly, they are shaft encoders that provide 512 to 2048 counts per revolution.

They are also commonly used as linear encoders with resolutions down to 0.005 inch. They are available in nearly any length desired. Most encoders are now optical, using molded assemblies consisting of a pair of LEDs, lenses, photo-sensors, and simple electronics. For rotary motion the assembly senses alternating opaque and clear lines on a rotating wheel. For linear motion the alternating lines may be on a fixed bar and the sensor assembly moves, or vice-versa. The pair of LED and photo-sensors are offset about one-half line width so that direction of motion may be sensed by observing the relative phase of the two outputs. Typical quadrature encoder outputs are a pair of digital logic signals that are nominally 90° out of phase. Some encoders also provide an

“index” pulse output once per revolution to provide absolute position information. Most modern encoders run from +5 volts and provide CMOS/TTL logic outputs and/or RS-422 differential logic outputs. RS-422 is recommended where possible because of its inherent noise immunity and the ability to run long distances. TTL logic levels should normally be restricted to cables less than ten feet in length. Quadrature encoders are available from Hewlett-Packard, US digital, and other sources.

The general purpose input structure permits differential input from line drivers (RS-422 levels) or single-ended logic level input (“TTL”) directly from most sensors. Programmable TTL resistive terminators provide for flexible high-quality signal termination.

There are three inputs per channel. For normal quadrature operation the two quadrature inputs are called X and Y. These inputs are sometimes called A and B lines from encoders. The X and Y inputs are normally driven 90° out of phase. There is also a control input on each channel called Z.

Its function is programmable, but it typically operates, if used, as an index or latch input.

There is a programmable prescaler for each channel that may be set for X1, X2 or X4 operation.

Vectored interrupts are fully supported. Interrupts are individually maskable. Selectable conditions are interrupt on borrow and interrupt on match (compare).

RS-422 differential input lines are www.ge-drive.com normally terminated with 120Ω resistors. Users may remove these socketed resistor networks or replace them with a different value if desired.

Each channel consists of a programmable input section, a 24-bit up/down counter block, a 24-bit capture/match register, and a 24-bit output latch. The output latch permits accurate “on-the-fly” reading of quadrature position values. The capture/match register may be used as either a hardware “capture” register to record exact mechanical position or to provide an interrupt any arbitrary programmable quadrature position value.

The all CMOS design is inherently low power. Up to 16 quadrature channels may be implemented in one host system slot.

Rexroth VT 2000-52 Bosch Rexroth Electrical Amplifiers

Features:

– Ideal for controlling direct-acting and pilot-operated proportional pressure control valves without electrical position feedback

– Differential Inputs

– Additional command value input, 0 to +9 V

– Ramp generator with separately adjustable rising and falling ramps

– Clock current output stage

– Clock Current Output Stage Reverse Voltage Supply Polarity Protection

– Short circuit protection

Function Description

The command value voltage can be applied to command value input 1 directly or via an external command value potentiometer using the regulated voltage of + 9 V of the power supply unit [8].

For this input the following conditions are valid: + 9 V = + 100 % 1).

Command value input 2 is a differential input [1] (0 to + 10 V). This input must be used if the command value is fed forward from an external electronic device with another reference potential (e.g. from the PLC).

This input must be used. When cutting in or out the command value voltage, take care to connect the two signal lines to or disconnect them from the input.

Prior to transmission, the two command values are summed [2] and fed to the potentiometer [3], which is available on the front panel of the card and is used as an attenuator to limit the maximum command value.

The Downstream Ramp Generator [4] generates a ramp-shaped output signal from the step input signal. The time constant of this signal can be adjusted to ramp up and ramp down using two potentiometers.

The specified ramp time is related to the command value step change of 100% and can be about 1 sec. or 5 sec. depending on the jumper setting. If a command value step change of less than 100 % is applied at the input of the ramp generator or when the attenuator [3] is set, the ramp time can be adjusted upwards and downwards.

or when the attenuator [3] is active, the ramp time is shortened accordingly.

With the aid of the external contact “ramp up/down”, the ramp time can be set to a minimum value (approx. 30 ms) for the upper and lower ramp times respectively.

The output signal of the Ramp Generator [4] is an internal current command value and is fed into the measurement socket “w” on the front panel of the card.

In addition, the command value is transferred to the current output stage [6] via the current regulator [5].

The current regulator [5] adds the value of the www.ge-drive.com bias current potentiometer “Zw” (R130) to the value of the ramp generator.

The current command value is modulated by the clock pulse encoder signal [7]. The clocked actual current value acts like a constant current and superimposes a jitter signal in the valve solenoid.

The actual current value through the solenoid valve can be measured at socket “I”. Here, a voltage of 800 mV corresponds to a current of 800 mA.
