Product Details
Product Overview
The IS200TREGH1BDB serves as a primary Trip Emergency Termination Board within the General Electric Mark VI control family. This Brand New original component provides the physical and electrical interface required to execute emergency shutdown sequences for utility-scale gas and steam turbines. It manages critical trip signals by coordinating high-capacity relays and surge suppression components, ensuring the control system maintains absolute authority over the turbine’s mechanical safety valves.

Engineering Advantages
-
Failsafe Relay Logic: Twelve large relays, arranged in pairs, provide redundant switching paths for the turbine trip solenoids. This configuration prevents a single relay failure from causing an accidental trip or, more critically, failing to close during an emergency shutdown.
-
Transient Surge Suppression: Ten integrated Metal Oxide Varistors (MOVs) actively clamp high-voltage spikes caused by inductive load switching. This protection layer shields the sensitive Mark VI control processors from back-EMF, extending the lifespan of the entire I/O rack.
-
High-Density Field Wiring: Two 24-point terminal blocks provide 48 total silver-plated connection points. These blocks accommodate heavy-gauge field wiring, ensuring secure, low-resistance termination for critical safety circuits.
-
Direct I/O Interfacing: Three jack connector ports allow for rapid connection to the Mark VI I/O packs. This design eliminates complex point-to-point internal wiring, reducing the risk of installation errors and simplifying maintenance during planned outages.
FAQs
-
Is this IS200TREGH1BDB board a brand new unit?
Yes. We supply this board as 100% Brand New original GE factory stock. It arrives in the original manufacturer’s packaging with all factory inspection seals intact to guarantee field reliability.
-
Can this board support Triple Modular Redundant (TMR) systems?
The TREG series boards typically support TMR applications by interfacing with three separate I/O packs. The three connector ports on the IS200TREGH1BDB allow the board to receive "voted" trip signals from the R, S, and T control cores.
-
What is the function of the red MOVs on the board?
The red MOVs (Metal Oxide Varistors) protect the board’s circuitry from voltage surges. They absorb excess energy when switching inductive loads, such as large turbine trip solenoids, preventing damage to the relays and upstream control electronics.
-
Do I need special tools to connect field wiring to the silver terminals?
Standard industrial screwdrivers suffice for the terminal blocks. However, GE recommends using ferruled wire ends to ensure maximum contact surface area and to prevent wire fraying within the high-vibration environment of a turbine control cabinet.

Tech & Buying Guide
Essential Best Practices for PLC Wiring and Installation in Industrial Automation
Successful control system deployment begins with thoroughly reviewing manufacturer technical documentation. Controllers from major brands like Allen-Bradley, Siemens, and Schneider Electric feature unique terminal layouts. Engineers must verify voltage requirements before connecting power cables to prevent catastrophic equipment damage. Standard line connections require strict adherence to regional electrical codes and proper wire color coding. Furthermore, panel builders should always establish a robust low-impedance ground connection using at least 16-AWG copper conductor tied directly to the main plant grounding grid.
