Key Features & Engineering Advantages

• Isolated Relay Outputs: Provides a 2500 VAC dielectric barrier between the control logic and the field equipment. This isolation prevents electrical noise or surges in the field from damaging the sensitive digital components of the Mark V system.

• Field-Changeable Components: The relays on the FCR2 board are mounted in high-quality sockets rather than being soldered directly to the PCB. This allows maintenance teams to replace a worn-out relay in minutes without needing specialized soldering tools, significantly reducing turbine downtime.

• High-Precision Timing: As a "Firing Circuit" board, it is engineered for deterministic signal timing, which is vital for the synchronized firing sequences required in gas or steam turbine operation.

• Seamless Mark V Integration: Designed specifically for the Mark V architecture, the board draws regulated power directly from the system bus and integrates natively with the Speedtronic software environment for diagnostics and status monitoring.

• Rugged Industrial Build: Built to withstand the continuous vibration and heat of a power plant environment, maintaining stable operation up to 70°C.
