🔧 Product Overview
The IS200TDBTH6A is a discrete input/output terminal board in the GE Mark VIe / Mark VI control system family. It is referred to as a “TDBT” (Terminal Discrete Board Terminal) type, combining discrete contact input circuits and relay outputs. It is used to interface field devices such as sensors and actuators with the controller, to isolate, condition, and relay signals for control and monitoring in turbine/industrial automation environments.

🏭 Applications
-
Interfacing field devices (contacts, sensors, switches) to turbine or generator control systems via discrete inputs.
-
Controlling actuators or alarms via relay outputs under the command of controller logic.
-
Used in distributed I/O architecture (e.g. Mark VIe) where discrete I/O packs communicate with R/S controllers.
-
Environments with electrical noise, where filtering and rejection of AC surges are required.
-
Systems requiring high channel count and mixed input/output discrete control in one module.
🌟 Key Advantages
-
Large number of discrete inputs (24) plus relay outputs (12) in one board, reducing external wiring complexity.
-
Robust input filtering and AC rejection to improve signal integrity in noisy environments.
-
Designed for compatibility with Mark VIe / Mark VI controller systems and distributed I/O packs.
-
Modular relay output option, allowing flexible use: may be used with or without relay accessory.
-
Durable build and industrial operating temperature range.
-
Convenient mounting options (DIN rail or panel) and standard terminal blocks facilitate field wiring.
