PRODUCT INFORMATION
Product Overview
The General Electric IS220PSVOH1B is a Mark VI / Mark VIe Servo Control Module. It provides an electrical interface between one or two I/O Ethernet networks and a TSVO servo terminal board. Input to the unit connects through dual RJ45 Ethernet ports. Operating power requires 28 V dc supplied directly through the terminal board.
The module accepts eight LVDT inputs and two pulse rate inputs while providing LVDT excitation. Output signals link through a DC-62 pin connector that attaches to the terminal board. The hardware works with an adjacent WSVO servo driver module to control two servo valve position loops. Faceplate diagnostic LEDs indicate operating status. An integrated infrared port allows local diagnostic serial communications.
