GE IS200WREAH1A Terminal Board

GE IS200WREAH1A Terminal Board

Description

IS200WREAH1A is an expansion sub-board for the GE Mark VIe turbine control system. It must be used in conjunction with the IS200TREAH1A trip terminal board and the IS220PPRA protection module to expand the access channels for external emergency stop contacts and auxiliary trip circuits, increase the signal access capacity of the terminal board, and collect multiple external stop hard contact signals and complete signal transfer transmission.

This sub-board adopts a standard board structure and is installed by plugging in, without the need for additional wiring and renovation. It can simultaneously collect multiple external emergency stop feedback signals and is compatible with the TMR three-out-of-two safety architecture of the entire machine. It is suitable for power station gas and steam turbine protection control cabinets. The wide-temperature surface mount circuit has strong anti-interference ability and, after expansion, can meet the wiring requirements of multiple external trip circuits. 

Features

Adapt to the IS200TREAH1A terminal board and be used as a complementary expansion sub-card.

Expand the multi-channel external emergency stop contact input channels and increase the circuit connection points.

Synchronize with the PPRA turbine protection module signals for interaction, matching the three-out-of-two protection logic.

Direct plug-in connection design, easy to disassemble and assemble, without the need to modify the original wiring.

-30℃ to +65℃ wide temperature range operation, industrial surface mount process is stable and reliable.

Standardized size, compatible with the same chassis module, neatly arranged.

Real-time upload of expansion circuit disconnection and contact abnormality fault signals.
