د.إ8,888.00

GE IS200DTRTH1ABA Simplex DIN-Rail Mounted Trip Transition Board (DTRT) is a specialized Printed Circuit Board (PCB) used in the GE Speedtronic Mark VI Turbine Control System.

Its core function is to act as a trip relay interface and transition board, linking the main trip logic processor to the final output relays that execute a turbine shutdown.1

🧠 Primary Function: Trip Interface

The DTRT board is essential for implementing the critical, high-speed trip functionality within the Mark VI system.2

  • Interface for Trip Logic: It provides the critical interface between the VTUR (VME Turbine Trip Unit Relay) I/O processor board and the DRLY (DIN-rail Mounted Relay Output) board.3
  • Trip Signal Transition: It handles the flow of trip commands, consolidating the trip signals originating from the VTUR board and passing them on to the DRLY board, which contains the physical relays that isolate or open critical circuits (e.g., fuel solenoids, main breaker trip coils) to shut down the turbine.
  • Simplex Application: The board is a Simplex (non-redundant) version, intended for use in control systems where Triple Modular Redundancy (TMR) is not required for the trip circuit.

⚙️ Key Technical Features

The DTRT board is designed for simplicity and reliability in the trip path:

Feature Details
System GE Speedtronic Mark VI Turbine Control System
Function Primary Trip Relay Interface/Transition Board
I/O Processor Interfaces with the VTUR (VME Turbine Trip Unit Relay) board.
Relay Board Connects to the DRLY (DIN-rail Relay Output) board.
Trip Capacity Designed to handle the control signals for up to six trip relays on the DRLY board.
Isolation Typically features optical isolation to protect the control electronics from the higher voltage relay circuits.
Mounting Designed for DIN-rail mounting for easy installation and connection within the control cabinet.
Connections Features multiple Sub-D pin connectors (e.g., J1 and J2 for VTUR) and a Euro-Block terminal for ground (SCOM).

The use of a separate transition board like the DTRT simplifies the wiring and modularizes the trip circuit, allowing the core control processor (VTUR) to be isolated from the high-current relay coil drive circuits.
