FUNCTIONAL DESCRIPTION:
IS200SSVPH2A is a Servo Input/Output Terminal Board Manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Servo I/O (SSVP) terminal board connects to two electro-hydraulic servo valves that actuate the steam valves. Valve position is measured with linear variable differential transformers (LVDT) or linear variable differential reluctance transformers (LVDR). SSVP is designed specifically for the PSVP I/O pack and the WSVO servo driver. It does not work with the VSVO board or the PSVO pack. The SSVP is a simplex terminal board. Dual redundancy is supported by using two SSVPs and fanning the inputs externally. Likewise, for TMR redundancy, use three SSVPs and fan the LVDT inputs externally by using jumpers to send the signal from one SSVP to another SSVP. A single 28 V dc supply comes in through plug P28IN. Plugs JD1 or JD2 are for an external trip from the protection module.
INSTALLATION:
Sensors and servo valves are wired directly to the TB1 I/O terminal block. The 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 the terminal block. External trip wiring is plugged into either JD1 or JD2. Each SSVP servo output can support one coil of a three-coil electro-hydraulic servo-actuator or paralleled coils from a two-coil servo. Based on the rated coil current, the user selects the current limiting resistor value to limit thermal stress on the current driver in case of a short output. Jumper, JP1 selects the resistor value for Servo 1 and JP2 is for Servo 2.

OPERATION:
The SSVP servo terminal board provides two channels consisting of bi-directional servo current outputs, six channels of LVDT/R position feedback, two channels of LVDT/R excitation, and one pulse rate input. There is a choice of one, two, or three LVDT/Rs for each servo control loop. The single pulse rate input is used for the steam turbine's primary speed and is not designed for a flow-type pulse rate input. Each servo output is equipped with an individual suicide relay under firmware control that shorts the current output to common when de-energized and recovers to nominal limits after a manual reset command is issued. Each servo output also includes an isolation relay on the SSVP to isolate a short from other servos that are connected in parallel to the suicided servo. Diagnostics monitor the output status of each servo voltage, current, and suicide relay.

How is the Servo Input/Output Terminal Board controlled?
Typically, the board is controlled using a microcontroller (such as Arduino) or a PLC (Programmable Logic Controller). These controllers send PWM signals or other control commands to the board, which in turn manages the servo motors connected to it.
What applications are suitable for this board?
This board is commonly used in robotics, CNC machines, automation systems, and any application where precise control of servo motors is required.
Do I need programming knowledge to use the Servo Input/Output Terminal Board?
Basic programming skills are often required to interface the board with a controller. You may need to write simple code to generate the necessary control signals for the board.
