FUNCTIONAL DESCRIPTION:

IS230TSVCH1A is a Servo Input/Output (TSVCH1A) Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The TSVC terminal board interfaces with two electro-hydraulic servo valves to control steam or fuel valve actuation. It measures valve position using linear variable differential transformers (LVDTs). Designed exclusively for the PSVO I/O pack and WSVO servo driver, the TSVC is incompatible with the VSVO processor. This terminal board supports simplex, dual, and TMR control configurations. It receives three 28 V DC supplies through plug J28, while plugs JD1 or JD2 connect to an external trip from the protection module. TSVCH1A T1 through T4 isolation transformers provide galvanic isolation between the WSVO's excitation output driver and the primary side of the LVDT/R position sensor.

INSTALLATION:

Sensors and servo valves are wired directly to two I/O terminal blocks. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wiring. A shield terminal strip attached to the chassis ground is located immediately to the left of each terminal block. External trip wiring is plugged into either JD1 or JD2. Each servo output can have three coils in TMR configuration. The size of each coil current is jumper-selected using JP1, 3, 5 for Servo 1, and JP2, 4, 6 for Servo 2.

OPERATION:

The TSVCH1A terminal board features two channels with bi-directional servo current outputs, LVDT position feedback, LVDT excitation, and pulse rate flow inputs. It supports up to eight LVDT valve position inputs, with one to four LVDTs selectable per servo control loop. Two pulse rate inputs facilitate gas turbine fuel flow measurement. Each servo output includes a firmware-controlled suicide relay that shorts the PSVO output signal to the signal common when de-energized, restoring to normal after a manual reset command. Diagnostic functions monitor servo voltage, current, and the suicide relay status.

Each servo output channel can drive one or two-coil servos in simplex applications or two or three-coil servos in TMR configurations. In two-coil TMR setups for 200# oil gear systems, two control packs drive one coil each, while the third has no servo coil interface. The system supports servo cable lengths up to 300 m (984 ft) with a maximum two-way cable resistance of 15 Ohms. To accommodate different servo coil types, jumper-selectable bi-directional current sources are available.

CONFIGURATION:

In a simplex system, jumper JP1 configures the coil current for servo 1, while jumper JP4 configures servo 2. In a TMR system, each servo output supports three coils, with coil currents selected using jumpers JP1�JP3 for servo 1 and JP4�JP6 for servo 2. All other configurations are performed via the ToolboxST application. Ensure power is applied to all three channels by verifying that switches SW1, SW2, and SW3 are ON and that the power indicators for P28R, S, and T are illuminated.

FREQUENTLY ASKED QUESTIONS:

What is a Servo Input/Output (TSVCH1A) Terminal Board?

A Servo Input/Output (TSVC) Terminal Board is an essential interface module used in automation and industrial systems to connect servo control systems with external devices. It plays a crucial role in enabling communication between the servo drives and external sensors, controllers, or equipment, ensuring seamless operation and precise control of servo mechanisms.

What are the primary functions of a TSVCH1A Terminal Board?

The TSVC Terminal Board is designed to facilitate the exchange of signals between a servo system and external components. It enables signal routing for control, feedback loops, and operational commands, ensuring that the servo system operates efficiently. This includes transmitting commands from controllers to servo drives and receiving feedback signals for monitoring and adjustments.

What types of input/output signals does the TSVCH1A Terminal Board support?

The TSVC Terminal Board supports a variety of signal types, including analog signals like 0-10V or 4-20mA for speed and position control, digital signals for ON/OFF commands or alarms, and encoder feedback signals that provide real-time data about the servo motor's position and speed. These diverse signal types make the TSVC versatile for various applications.
