Functional Design and Signal Termination
The GE IS200SPROS1ADD connects directly to the protection backplane of the cabinet. It accepts field wiring from speed and temperature sensors. Then, this board passes conditioned signals to the protection module. Each channel includes over-voltage clamping for transient protection. Therefore, the IS200SPROS1A provides reliable signal termination for critical turbine protection circuits.
Installation and Compatibility Notes
You must tighten all terminal screws before powering up the system. The GE IS200SPROS1A fits exclusively into Mark VI series cabinets. Always replace faulty units with identical GE board revisions. Additionally, verify the sensor wiring matches the terminal labels. This practice prevents false trips due to incorrect connections.
