Description

The IS200TSVOH1B is a specialized servo termination board engineered for the General Electric Mark VI Speedtronic turbine control system. It acts as the physical interface connecting the VSVO I/O processor to two electro-hydraulic servo valves regulating gas or steam turbine fuel and steam valves.

The IS200TSVOH1B terminal board accepts inputs from two bidirectional servo current sources across two independent I/O channels. For precise valve positioning monitoring, it accommodates up to six Linear Variable Differential Transformers (LVDT) or Linear Variable Differential Reluctance (LVDR) feedback sensors, supporting high-select, median-select, or low-select algorithms. The board processes pulse rate input frequencies between 2 Hz and 14 kHz, and connects seamlessly to the VME rack via dedicated cables and plugs for Simplex or Triple Modular Redundant (TMR) control schemes.

Features

Supports Simplex configurations using JR1 connector and TMR configurations via JR1, JS1, and JT1 connectors.
Equipped with barrier-type terminal blocks mounted on one long side of the board.
Accommodates up to six LVDT/LVDR position feedback sensor attachments (three per terminal block).
Features dedicated external trip inputs via JD1 and JD2 plugs from the protection module.
Includes jumper-selectable (JP1-6) bidirectional current sources to adapt to various servo coil configurations.
Integrated shield termination strips connected directly to chassis ground located adjacent to each terminal block.

Applications

Steam turbine control valve modulation.
Industrial gas turbine fuel valve regulation.
Electro-hydraulic actuator interfacing in Mark VI Speedtronic control systems.

Installation Guidelines

Wiring Capacity: Ensure all field wiring connected to the 24-position terminal blocks does not exceed #12 AWG. Secure the blocks using the two integral retention screws.
Grounding and Shielding: Terminate cable shields directly at the shield termination strips located to the left of each terminal block to ensure proper chassis grounding and mitigate EMI/RFI noise.
Coil Configuration: Set jumpers JP1 through JP6 according to the specific bidirectional current requirements of the connected servo valves before powering the loop.
ESD Protection: Always utilize grounding wrist straps and anti-static mats when handling or unboxing this static-sensitive surface-mount assembly.

#Mark VI #Servo Terminal Boards

What is the maximum supported cable length for the servo connections?

The board supports a maximum servo cable length of up to 300 meters (984 feet), provided the two-way cable resistance does not exceed 15 ohms.

How are the servo coil outputs configured for Simplex versus TMR applications?

In Simplex mode, each output channel drives one or two coil servos. In TMR mode, each channel drives two or three coil servos, with current configurations adjusted via jumpers JP1 through JP6.

What type of terminal blocks are used on this specific board variant?

This variant utilizes barrier-type terminal blocks mounted along one long side of the board. For box-type terminals, the DSVO board series must be used instead.

What specific system faults can this terminal board detect?

The board monitors and flags servo currents that are out of limits or non-responsive, regulator feedback signals that exceed operational thresholds, and failed onboard ID chips.
