PRODUCT INFORMATION
Product Overview
The General Electric IS200TSVCH1A is a Servo I/O Terminal Board within the Mark VI / Mark VIe series. This circuit board provides physical signal termination and interfacing for two electro-hydraulic servo valves. It functions alongside the Mark VIe WSVO servo driver and the PSVO input/output pack. The board is an A-rated functional revision of the parent IS200TSVCH1 design.
The assembly incorporates an internal power supply rated at 28 V dc located at the base. Two excitation outputs designated TB4/3 reside adjacent to the power supply. Field wiring terminates at two 24-point barrier terminal blocks supporting up to number 12 AWG wiring. A grounding shield bar runs along the left edge, and components feature protective conformal coating.
