GE Mark VI Series IS200TRPLH1A Primary Trip Terminal Block

Specification

Part Number: IS200TRPLH1A

Manufacturer: General Electric

Product Type: Primary Trip Terminal Block

Series: Mark VI

Part of the Mark VI GE Speedtronic series, the GE Mark VI IS200TRPLH1A is used as a primary trip terminal board.

General Electric's IS200TRPLH1A board assembly is used in the company's Mark VI system for conditioning industrial gas and steam turbine systems.

The Mark VI was one of the last Speedtronic systems developed and released by General Electric.

This board is typically found only on steam turbines. It is compatible with the Mark VI and Mark VIe systems.

It is the terminal card for the primary stroke on large steam turbines. It is the primary overspeed protection on large steam turbine systems.

The board is controlled by the Turbine Protection Controller card, which is usually a VTUR or PTUR board.

It also works in conjunction with the TREL board to provide an emergency/primary interface to the ETD.

The TRPL board feeds the negative side of the 125 VDC to the trip solenoid, while the TREL board provides the positive side. Up to three trip solenoids can be connected to these boards.

The boards have two large terminal blocks with a total of 48 connector points.

Also included are MOV diodes, resistors, transistors, integrated circuits, jumpers, and nine magnetic relays, as well as 3D housing connectors and other plug connectors.

Three voting circuits are connected via relays to three trip solenoids.

The trip circuits include solenoid suppression and voltage monitoring, and the solenoids vote using two-thirds contacts.

What is the purpose of the IS200TRPLH1A?

The IS200TRPLH1A is a termination card for the primary trip on larger steam turbines. On larger steam turbines it is the primary overspeed protection.

How many connector pins does the IS200TRPLH1A have?

There are 48 connector points on the board.
