Main Functions

Field signal termination & physical interface: Serve as the hardware bridge between field discrete devices and PDIO I/O processor packs. It receives dry‑contact digital input signals and outputs relay control signals via onboard terminal blocks and multi‑pin D‑connectors.
Triple Modular Redundancy (TMR) signal routing: Support triple‑modular‑redundant I/O architecture for high‑safety turbine protection; distribute field signals to three redundant I/O packs for voting logic processing to avoid single‑point failure.
Discrete input acquisition: Accept digital contact inputs from site devices such as limit switches, emergency stop buttons, interlock contactors, collect status signals and transmit them to the main controller.More products: www.plcva.com

General Electric IS200TDBTH6ACD Discrete Bridge Terminal Board

Relay contact output: Equipped with form‑C relay outputs to drive field actuators including solenoid valves, trip relays and auxiliary contactors for turbine interlock and protection actions.
Signal surge & noise suppression: Integrate transient‑protection and filtering circuits, suppress industrial surge voltage and electromagnetic interference, protect backend I/O modules from field‑side electrical damage and guarantee signal integrity.
Hardware diagnostic & status indication: Provide channel‑level LED status feedback; support system software diagnosis for open‑circuit, short‑circuit and board‑level faults, facilitating on‑site troubleshooting and predictive maintenance.
Cabinet rack‑mount installation: Designed for installation inside Mark VI/VIe control cabinet; cooperate with IONet bus communication, support hot‑swap related system maintenance operations.
