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.

Key Features:

#Mark VI #Servo Terminal Boards

Qual é o comprimento máximo de cabo suportado para as conexões do servo?

A placa suporta um comprimento máximo de cabo de servo de até 300 metros (984 pés), desde que a resistência do cabo bidirecional não exceda 15 ohms.

Como as saídas das bobinas do servo são configuradas para aplicações Simplex versus TMR?

No modo Simplex, cada canal de saída aciona um ou dois servos de bobina. No modo TMR, cada canal aciona dois ou três servos de bobina, com as configurações de corrente ajustadas via jumpers JP1 a JP6.

Que tipo de blocos terminais são usados nesta variante específica da placa?

Esta variante utiliza blocos terminais do tipo barreira montados ao longo de um dos lados longos da placa. Para terminais do tipo caixa, deve-se usar a série de placas DSVO.

Quais falhas específicas do sistema esta placa terminal pode detectar?

A placa monitora e sinaliza correntes de servo fora dos limites ou não responsivas, sinais de feedback do regulador que excedem os limites operacionais e chips de identificação onboard com falha.
