IS200TRLYH1BGF frequency converter  

IS200TRLYH1BGF is a TRLY relay output terminal board for Speedtronic Mark VI/VIe turbine control system, responsible for driving unit interlocking and alarm circuit relays.
Product Features
1. Triple redundant TMR architecture, with 2 out of 3 voting for the three channel signal, ensures that a single point of failure will not cause misoperation and meets the safety protection requirements of the unit
2. Equipped with multiple sets of electromechanical relays, it can drive on-site solenoid valves, sound and light alarms, and remote switch signals
3. Support relay coil status diagnosis, detect coil breakage, short circuit, and contact welding faults, and quickly report alarms
4. Electrical isolation between channels to resist strong electromagnetic interference from power plants and prevent the spread of cross channel faults
5. Cabinet slot installation with three anti coating, suitable for power station control cabinet environment, easy replacement of spare parts
