Description

The IS400TDBTH2A is a discrete input/output terminal board designed for the General Electric Mark VIe control system. This component serves as a robust interface for digital signals, facilitating the connection between field wiring and the I/O processor modules. It accommodates multiple dry contact inputs and provides relay outputs to support comprehensive industrial automation control loops. Engineered for high reliability in demanding environments, the module functions efficiently within steam/gas turbine control, power generation assets, and process plant applications, ensuring seamless system compatibility and signal integrity across the Mark VIe platform.

Features

Provides direct termination for external field wiring with secure screw clamp connections.
Supports discrete contact inputs and integrated relay outputs on a single board footprint.
Implements onboard optical isolation to protect internal control electronics from field-side voltage surges.
Features diagnostic LEDs to deliver immediate visual status of relay coil states and input channels.
Designed for compact panel mounting with high-density channel layout to optimize enclosure space.

Applications

Utility and industrial gas turbine control systems.
Steam turbine sequence control and safety interlocking.
Balance of Plant (BOP) discrete device monitoring.
Emergency shutdown (ESD) and critical interlock validation.

Installation Guidelines

Mounting: Securely mount the board vertically inside the enclosure using the designated standoff mounting holes or standard DIN rail hardware options.
Grounding: Ensure the chassis ground terminal is connected directly to the low-impedance master enclosure ground bus.
Wiring: Route discrete AC/DC field wiring separately from low-voltage network cables to mitigate electromagnetic interference (EMI).
Isolation Check: Verify all field dry contacts are completely unpowered before connecting to prevent damage to the internal optical couplers.

#Discrete Input/Output Modules #Mark VIe

Does this terminal board require external power for the contact inputs?

No. The board provides internal excitation voltage for the dry contact inputs, eliminating the need for an external interrogation power supply.

What is the primary function of the diagnostic LEDs on the board?

The LEDs provide a direct visual indication of the logic state for each digital channel, showing whether an input is closed or a relay output is energized.

How does the board connect to the core I/O processor pack?

It utilizes standard system cables attached via onboard multi-pin connectors to transmit conditioned parallel signals to the processing unit.
