Frequently asked questions

1.What is IS200TREAH1A

It is a turbine emergency trip terminal board developed by GE under the Mark Vle series

2.What should I do if I need to remove the board for servicing?

If you need to service the TRA fanning jumpers or any other components, you must first remove the option card. Follow the outlined procedure to carefully detach and later reattach the WREA to the board

3.How do I properly align the option board with the terminal board?

Align the connectors on the option board with those, ensuring the bottom of the WREA board (where the configuration jumpers are located) is correctly positioned. The connectors are keyed and will only mate when properly aligned, preventing incorrect installation

4.What indicates that the WREA is fully mounted to the board?

It is fully mounted when it cannot be pushed anv farther This ensures a secure connection.Press down firmly on the four screw heads surroundina the connector area to

seat the connection properly.

Product Applications

Power Generation and Energy: Serving as a critical core for emergency trip control and protection in gas/steam turbine generator sets.

Nuclear Power and High-Risk Chemicals: Meeting the stringent standards of fault tolerance and system safety in the nuclear industry and chemical plants through its supported Triple Redundancy (TMR) voting mechanism.

Oil and Gas: Used for overspeed protection, vibration monitoring, and emergency safety shutdown in large pipeline compressor units.

Metallurgy and Heavy Industry: Ensuring equipment safety in the event of sudden failures in the drive control of large power equipment.

Features

Customer Input Terminals: Available through two 24-point pluggable barrier terminal blocks or 48 pluggable Euro-style box terminals (H3A or S3A),

Pulse Rate Devices: Six passive pulse rate devices (supporting up to three shafts with two sensors each) that sense a toothed wheel to measure turbine speed.

Solid-State Output Contacts: Three TMR voted 24 V DC output contacts designed to trip the system.

Voltage Detection Circuits: Four circuits for detecting voltages between 24-125 V DC, used for monitoring trip strings

Contact Inputs: Four 24 V DC contact inputs on WREAH1A or WREAS1A provide additional hardware or conditional trip inputs, with wetting power supplied via the JH1 connector on WREA.

Speed Repeater Outputs: Each of the six-speed inputs has a corresponding repeater output that reproduces the speed pulse rate signals, transmitted through an

RS-232 or RS-422 interface
