The Real-World Problem It Solves
Unprotected 125VDC power runs cause cascading failures in turbine cabinets. One shorted field device takes down the entire control system without isolation. stops this by providing fused outputs and ground fault detection to contain faults locally.
Where you’ll typically find it:
- Gas/steam turbine ESD & emergency trip solenoid power
- Mark VIe controller & I/O rack battery-backed 125VDC bussing
- Offshore platforms & power plant safety instrumented system (SIS) power
Bottom line: This board prevents a single point of failure from crashing your turbine control system.
Hardware Architecture & Under-the-Hood Logic
is a passive power distribution board with discrete fault-sensing circuitry—no on-board microprocessor. It relies on analog comparators and fuse monitors for status.
