IS200SSVPH1A is a Servo I/O Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. Two electro-hydraulic servo valves are connected to the Servo I/O (SSVP) terminal board, which operates the steam valves. Linear variable differential transformers (LVDT) or linear variable differential reluctance transformers are used to measure valve position (LVDR). The PSVP I/O pack and the WSVO servo driver are the only devices for which SSVP is intended. Both the VSVO board and the PSVO pack are incompatible with it. A simplex terminal board is the SSVP. Using two SSVPs and externally fanning the inputs supports dual redundancy. Use three SSVPs and externally fan the LVDT inputs by using jumpers to transmit the signal from one SSVP to the next for TMR redundancy. Plug P28IN allows a single 28 V dc supply to be connected.
The SSVP servo terminal board offers one pulse rate input, six channels of LVDT/R position feedback, two channels of LVDT/R excitation, and two channels of bi-directional servo current outputs. It accepts input from up to six LVDT valve position inputs and offers four excitation outputs. For each servo control loop, there is a choice of one, two, or three LVDT/Rs. The steam turbine's primary speed is controlled by the single pulse rate input.
Each servo output has its own suicide relay, which is managed by firmware, and which, when de-energized, shorts the WSVO output signal-to-signal common before returning to normal limits in response to a manual reset instruction. In order to prevent a short from spreading to additional servos connected in parallel to the suicided servo, each servo output also has an isolation relay. Each servo's output condition, including its voltage, current, and suicide relay, is monitored via diagnostics.
In a simplex system, servo 1 is configured for the correct coil current with jumper JP1. Servo 2 is configured with jumper JP2. In a TMR system, one servo from three different SSVPs provides the drivers needed for three coils. In this case, the LVDT inputs are fanned externally to all three SSVPs. All other servo board configuration is done from the ToolboxST application.
