GE DS200GSIAG1A | Single servo I/O terminal board

GE DS200GSIAG1A is a single servo I/O terminal board manufactured and designed by General Electric, belonging to the Mark VI series used in GE Speedtronic control systems.

· Servo output: has two servo outputs.

· Position sensor I/O: Provides I/O for six LVDT position sensors.

· Pulse rate input: There are two active pulse rate inputs used for flow monitoring.

· Onboard ID chip: In order to facilitate system diagnosis and identification, connectors JR1 and J5 are connected to signals from the onboard ID chip.

· Servo valve coil configuration: The servo valve coil resistance and required coil current ranging from 22W to 1000W are selected on DSVOH1B through jumpers JP1 and JP2. For example, jumper 120B provides approximately 120mA of coil current.
