MeloAuto-Trusted PLC & DCS Parts Supplier
The GE IS200SCLTH1A and GE IS200SCLTH1AAB serve as core analog terminal boards for turbine control systems. These modules belong to the Mark VI series from General Electric. They provide termination points for critical analog signals within the cabinet. Consequently, these boards simplify field wiring to the main analog processor.

Functional Design and Analog Termination
The GE IS200SCLTH1AAB connects directly to the analog backplane of the cabinet. It accepts 4-20 mA and voltage signals from field transmitters. Then, this board passes conditioned signals to the processor module. Each channel includes a precision resistor for current-to-voltage conversion. Therefore, the IS200SCLTH1A provides accurate signal termination for core analog measurements.
Installation and Compatibility Notes
You must tighten all terminal screws before powering up the system. The GE IS200SCLTH1A fits exclusively into Mark VI series cabinets. Always replace faulty units with identical GE board revisions. Additionally, verify the signal type matches the channel configuration. This practice prevents measurement errors due to incorrect scaling.
