IS200TREGH5B

About the IS200TREGH5B

The IS200TREGH5B is a printed circuit board manufactured by General Electric shell company GE Industrial Systems for use in their Mark VI Speedtronic control system series. This PCB is more explicitly defined as a Gas Turbine Emergency Trip Terminal Board, and comes standard with the Mark VI Speedtronic series' set of fully programmable software maintenance tools, as well as both software and hardware limit checking. This is considered a revised version of the parent IS200TREGH5B Emergency Trip Terminal Board, modified through its inclusion of a singular B-rated functional revision.

Hardware Tips and Specifications

The IS200TREGH5B Gas Turbine Emergency Trip Board has made as a part of the greater Mark VI Speedtronic series, and therefore remains compatible with a slew of other Mark VI Speedtronic products. One such product is the VPRO protection module, which is entirely responsible for controlling the TREG PCB. The only connections that exist between this TREG printed circuit board and the VPRO protection module are its trip solenoid connections as well as its J2 power cable. A servo valve clamp function is supplied in simplex systems, and extends from the J1 connector through to the TSVO associated terminal board. While the J1 connector is relevant in terms of VPRO module connections, a set of other crucial connectors exist, stemming from the base board of the IS200TREGH5B. The TREG connectors JX1, JY1, and JZ1 all have individual ID devices for I/O controller interrogation purposes. These connectors all have specialized voltage functions, as outlined in original General Electric Instructional Manual Material. For example, the JZ1 connector attached to the TREG PCB provides feedback circuit and economizing relay power to the greater drive assembly. The ID devices associated with these crucial connectors are read-only chips coded with a series of specific information, including the TREG board's serial number, board type, plug location, revision history, and plug locations. 

While a number of hardware components and connectors need to be emphasized before making a purchase decision of this TREG Gas Turbine Trip Board, it remains equally important to understand the function of the board itself. The IS200TREGH5B provides power for up to three emergency trip solenoids, and provides positive dc power to greater assembly solenoids, while also utilizing nine of its twelve attached relays to provide additional trip solenoid support and processing power. As mentioned before, the IS200TREGH5B is a modified version of the original IS200TREGH5 parent board. The H5B grouping designation asserts the IS200TREGH5B's status a special version PCB for use in systems featuring redundant TREG boards.

The IS200TREGH5B Gas Turbine Emergency Trip board is a powerful printed circuit board, and is rightfully protected beneath a layer of conformal-style PCB coating. Conformal-style printed circuit board coating is much thinner than the competitive normal PCB coating alternative, although it provides a much more comprehensive and fully-fledged protective coating than the basic level normal PCB coating would.
