Product Description

The IS200TRLYH1C is a board component created by General Electric for the Mark VI system.  The MKVI is a flexible management platform designed for multiple applications, including gas and steam heavy-duty turbines.  The system features high-speed, networked controllers and I/Os that can be used for simplex and triple redundant systems. The system uses industry-standard Ethernet communications for controllers, I/O, and the operator interface (HMI.) The Mark VI utilizes a set of software for programming, trending, configuration, and analyzing diagnostics, including the CIMPLICITY graphics display system and the Control System Toolbox for maintenance.  

The IS200TRLYH1C is a Relay Output terminal board with contact sensing.  The board has twelve plug-in magnetic relays. These fall into three distinct categories:

• Relays one through six are Form-C contact outputs.  These drive external solenoids

• Relays seven through eleven are also Form-C contacts.  However, these are unpowered.

• Relay twelve is an isolated Form-C contact with a non-fused power supply.  This relay is used for ignition transformers.

The IS200TRLYH1C is built with four female cable connectors.  These are labeled JA1/JR1/JS1/JT1. Connectors are used to connect to the VCCC or VCRC board.  There are four female plug connectors on the board for the connection of solenoid power. The board has twelve fuses placed on the board in two lines of six. The board also has MOVs (metal oxide varistors) to aid with surge suppression.

The IS200TRLYH1C is notched in two corners.  The board has several factory-made drill marks located at several locations within the body of the board.  Other components on the board surface include resistors, diodes, and jumper switches.
