Device Overview

The CM-TCN Smart Temperature Monitoring Relay is designed to meet different customer needs with one device.

Its LCD display provides intuitive status updates, and through Near Field Communication (NFC) you can adjust settings simply from your smartphone, making installation quicker and more intuitive.

With a measuring range of -200…+850 °C, the device is compatible with a wide range of sensor types and offers storage for predefined and user-defined configurations for common motor or transformer monitoring applications.

Wireless configuration and status checking is possible using ABB’s EPiC application.

Using the app, parameters can be quickly set and stored in the app or copied to other www.ge-drive.com CM-TCN devices, even in the absence of power.

In addition, parameters can be uploaded to the cloud or shared via email within seconds.

Temperature monitoring relays are typically used in the following applications:

Motor and system protection

Control cabinet internal temperature monitoring

Motor monitoring

Transformer monitoring

Ambient temperature monitoring

Process variable temperature limits

Bearing temperature monitoring

Coolant Temperature Monitoring

Packaging Industry

Air conditioning systems

Ventilation systems

Heat pumps

Hot water supply

LCD display and symbol-based menu structure

Unit with LCD display.

Display:

– Ensures intuitive and quick setup with the help of a symbol-based menu structure. Configuration files for various applications are also available. Each parameter can also be modified individually and stored as a user profile for future re-use.

– Permanent display of the device status and all currently measured temperatures. Detailed diagnostic information helps to quickly identify problems.

-Provides a wide range of operating parameter calculations, helping to reduce maintenance costs.

Uses symbols rather than text throughout the menu structure.

Near Field Communication (NFC)

Each device in the Smart Monitoring Relay series has a built-in NFC antenna, which makes it possible to use the

ABB’s EPiC mobile smartphone app allows the device to be parameterized via NFC.

To read or write data, the smartphone needs to touch the surface of the CM-TCN. The connection is only active when data is being transferred. In contrast to Bluetooth, there is no continuous communication between NFC and the device.

ABB EPiC Smartphone App

EpiC, or “Electrification Product Intuitive Configurator”, is a mobile application that allows configuration and checking the status of ABB low voltage products. The app is free and can be downloaded on Android and iOS. Registration is required to use it.
