ABB CMA132 (3DDE300412) Generator Relay Terminal Board

Description

The ABB CMA132 (3DDE300412) Generator Relay Terminal Board is a component of the Advant DCS/800xA product series, designed to connect generator protection relays to central control systems. It delivers core functions including signal isolation, power distribution, and reliable data transmission, supporting generator monitoring, protection, and control operations for both AC and DC generator types. Equipped with 16 input channels, it accepts a wide range of input types: thermocouples, RTDs, mV, mA, V, and potentiometers, with a 16-bit resolution for precise signal capture. Its input signal ranges cover thermocouples from -200 degrees Celsius to +1800 degrees Celsius, RTDs from -200 degrees Celsius to +800 degrees Celsius, and mV signals from -10 V to +10 V. The board features 1500 VAC isolation between input channels and power supply to prevent cross-interference, and uses Modbus RTU communication protocol for seamless system integration. With dimensions of 230 mm x 160 mm x 60 mm and a weight of 1.2 kg, it is classified as a small device (WEEE category 9b, no external dimension over 50 cm), and complies with RoHS standards. It also offers expandable input and output modules for customized configurations, and features industrial-grade design for stable operation in harsh environments.
