GE IS200TDBTH6ABC | Discrete Bridge Terminal Board |

Product type: Digital Bridge Terminal Board (Discrete I/O Terminal Board), used in conjunction with PDIO Digital I/O Processor Card, interface board between on-site switch devices and controllers

Core Functionality
On site discrete switch signal wiring terminal interface, connected to limit switches, relay contacts, solenoid valves, local buttons and other on-site switch equipment.
Complete signal conversion, surge suppression, EMI protection, protect the backend PDIO I/O processing card, and filter transient high voltage interference in the field circuit.
Support TMR the third mock examination redundant system architecture, which can be used for gas turbine/steam turbine interlocking, tripping, auxiliary logic circuit.
Onboard relay, MOV varistor transient absorption circuit, equipped with circuit diagnosis, supporting SOE event timing recording signal path.
By connecting high-density ribbon connectors between boards to PDIO processor modules, signal routing and distribution between on-site contact signals and controllers can be achieved.
