Meta Description
GE IS230TDBTH6A TDBT discrete input/output terminal board for Mark VIe turbine control. 24 group-isolated contact inputs, built-in relay outputs, fully tested, global shipping for power plant MRO spares.
IS230TDBTH6A is the TDBT discrete I/O terminal board designed for GE Mark VIe Speedtronic turbine control systems. It is a combined input and output termination board, handling both dry contact input signals and relay discrete output signals for turbine safety interlock and auxiliary equipment control. This board interfaces field limit switches, pressure switches, solenoid valves and relay actuators to the matched Mark VIe discrete I/O pack, widely used in gas turbines, steam turbines, combined cycle power plants, oil & gas and petrochemical compressor systems.
Manufacturer: GE (GE Vernova) Series: Mark VIe Part Number: IS230TDBTH6A Product Type: TDBT Discrete Input / Output Terminal Board Input Channels: 24 group-isolated dry contact inputs, 125VDC nominal Onboard Components: 12 integrated relays for discrete output control Mounting: DIN rail mount Function: Combined discrete I/O field wiring termination
This PCB terminal board is equipped with dual terminal blocks TB1 and TB2 for high-density field wiring. Every input channel has built-in surge suppression and EMI filter circuits using MOV components, to absorb voltage transients and reduce high-frequency electrical noise inside turbine hall environments. The board features no configurable jumpers, simplifying commissioning and reducing onsite configuration errors. The onboard relays drive external solenoids and interlock devices, executing on/off safety commands from the Mark VIe controller. It supports group isolation for input circuits to prevent cross-channel interference.
We supply new, surplus and refurbished IS230TDBTH6A terminal boards. Every board undergoes continuity, relay and signal integrity testing before shipment and comes with warranty. We offer worldwide shipping for plant MRO maintenance, system retrofits, emergency spare replacement and project commissioning.
