System compatibility

IC3600QSPA103B belongs to GE Fanuc Speedtronic Mark I / Mark II turbine control series. Compatible with Speedtronic Mark I/II control rack, power supply and other signal/protection boards. Widely applied on gas/steam turbine power generation control system.

Function

IC3600QSPA103B is analog signal processing and protection circuit board manufactured by GE Fanuc for old Speedtronic turbine control system. It receives weak analog signals from field transmitters and sensors, performs amplification, filtering and threshold comparison. When measured value exceeds preset limit, it outputs trip or alarm signal for turbine safety protection. Test points on PCB allow maintenance technicians to measure signal level for troubleshooting.

Installation

Follow lockout/tagout safety procedure before installation. Fully cut off turbine control cabinet power. Insert IC3600QSPA103B board into rack slot and lock retainer. Verify all backplane contact pins. Power on, use multimeter at test points to check analog signal and threshold level.

Interface

Speedtronic rack gold-edge backplane connector, field analog signal terminal block, onboard test point terminals for GE Fanuc IC3600QSPA103B.
