ABB CMA132 Generator Relay Terminal Board

ABB CMA132 Generator Relay Terminal Block is essential for protecting and supervising generators in power generation and distribution installations. This terminal block is a key power system maintenance component that provides connection and control functions.

It is connected to multiple sensors through its input interface. Current sensors measure the generator output current, voltage sensors monitor the terminal voltage, and temperature sensors detect the temperature of the generator windings or key components. The board then converts the physical quantity from the sensor into an electrical signal (usually an analog signal).

Function & Features

• Sensor connection: The ABB CMA132 board is connected to various sensors through its input interface. These sensors are distributed in the generator and related circuits. For example, the current sensor is used to measure the current output by the generator, the voltage sensor is used to monitor the terminal voltage of the generator, and the temperature sensor is used to detect the temperature of the generator winding or key components.

• Signal conversion: The ABB CMA132 board sensor converts the collected physical quantities (such as current, voltage, temperature, etc.) into electrical signals, which are usually analog signals.

• Warning output: The ABB CMA132 board also sends an alarm signal through the output interface. This signal can be connected to an audible and visual alarm, a monitoring system or a remote control center, etc., to remind the staff to deal with it in time.
