Product Description
ABB CMA131 (Order No.3DDE300411) is a relay output board of SYNPOL-D series, designed for gas turbine & steam turbine protection and sequence control. It serves as the core I/O module for ABB turbine control system. This board integrates multiple relay output circuits for turbine interlock protection, trip circuits, alarms and auxiliary equipment logic drive. Equipped with hardware fault diagnosis and status feedback, it adopts integrated terminal block design and orange rail-mounted base. With excellent vibration and EMC resistance, it is developed for protection & control of gas and steam turbines in power plants and acts as critical spare part for SYNPOL-D system.
