GE IS200TSVCH1AED Servo Input/Output Terminal Board

Product Description

Item	Description
Product Name	TSVC Servo I/O Terminal Board
Part Number	IS200TSVCH1AED
Main Functions	As the interface terminal board in the servo control loop, it connects the PSVO I/O module with the servo valve (output) and position feedback sensor (such as LVDT, input) on site.
Supporting I/O Modules	Must be used with the PSVO Servo Control I/O module.
System	In the Mark VIe control system, the complete servo control chain is: controller → PSVO module → TSVC terminal board → servo valve/sensor.
Compatibility and Redundancy	Supports TMR (Triple Modular Redundancy) configuration. In a TMR system, three PSVO modules can be connected to three independent connectors (JR1, JS1, JT1) on the same TSVC terminal board.
Key Features	- Output: Provides a high-precision analog signal (e.g., ±10 V DC or 4-20 mA) to drive a servo valve. - Input: Receives feedback signals from position sensors. - Signal Conditioning: The board contains the necessary circuitry for signal conditioning and protection.
Physical Connection	- Directly plugs into the PSVO I/O module via a DC-37-pin connector. - Pluggable, shielded terminal blocks are used on the field side for easy installation and maintenance.
Power Supply	The operating power is provided by the connected PSVO I/O module through the backplane connector.
Documentation Reference	Detailed information is found in the "PSVO Servo Control" section of the document (pages 451-472).

System Integration

Used with the PSVO module to form a complete servo control loop.
Supports Simplex (single-channel) or TMR (triple redundant) configurations in Mark VIe systems.
Configuration and diagnostics are available through ToolboxST software.

Diagnostics and Maintenance

Self-diagnostics detect output short circuits, open circuits, overloads, and other faults.
Status is displayed via the PSVO module's LED indicators and the ToolboxST interface.
Online replacement is supported, facilitating easy maintenance.
