GE IS200DRLYH1ADC Relay Output Terminal Board

Feature & Principle

It is a simplex relay output terminal board for GE Speedtronic Mark VI rack. It receives discrete command signals from the main processor board via 37-pin cable, and drives internal electromechanical relays to output isolated dry contacts. Each channel is Form-C changeover contact, can realize trip command, alarm indication and actuator on-off control. It cannot be used for TMR redundant control, two DRLY boards can be matched to expand output points. Conformal coating protects the circuit against humidity and corrosive gas in power plant cabinet environment.
