PRODUCT INFORMATION
Product Overview
The General Electric IS200TRLYH1B is a Relay Terminal Board designed for Mark VI turbine control systems. This unit operates as the B revision within the TRLY terminal board family. It provides voted coil drive feedback across its integrated relay circuits. Two barrier terminal blocks line the left board edge. Each block offers twenty-four metal screw terminals for external field wiring connections. Together they deliver forty-eight total silver contact connection points.
Four connector ports are positioned along the right border of the printed circuit board. Circuit protection incorporates round red metal oxide varistors alongside discrete switching transistors. The hardware features sealed mechanical plug-in relays protected by transparent cubic enclosures. Power distribution includes six fused circuit branches along with one unfused branch. It mounts securely in industrial enclosures via standard DIN-rail hardware. The design supports triple module redundant operation per GE manual GEH-6421Q.
