FUNCTIONAL DESCRIPTION:

IS210DSVOH1B is a Simplex Servo Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Control Systems. The Simplex Servo Input/Output (DSVO) terminal board is a compact terminal board designed for DIN-rail mounting. This board has two servo outputs, I/O for six LVDT position sensors, and two active pulse rate inputs for flow measurement. Servo coil currents ranging from 10 to 120 mA can be selected using jumpers. DSVO connects to the VSVO processor board with a 37-pin cable, which is identical to those used on the larger TSVO board. The terminal boards can be stacked vertically on the DIN rail to conserve cabinet space. Two DSVO boards can be connected to the VSVO if required. Only a simplex version of this board is available.

The on-board functions and high-frequency decoupling to ground are the same as those on the TSVO. High-density Euro-Block type terminal blocks are permanently mounted to the board with six screws for the ground connection (SCOM). Connectors JR1 and J5 connect to signals from onboard ID chips that identify the board to the VSVO for system diagnostic purposes. Two versions of the DSVO, H1B and H2B, are available. The H1B is a direct replacement for the previous H1A design. The H2B is certified by UL for Class 1 Division 2 applications.

INSTALLATION:

Mount the plastic holder on the DIN rail and slide the DSVO board into place. Connect the wires for the servo I/O directly to the terminal block. The Euro-Block type terminal block has 36 terminals (DSVOH1A) or 42 terminals (DSVOH1B, H2B) and is permanently mounted on the terminal board. Typically #18 AWG shielded twisted pair wiring is used. Six screws, 31-36 are provided for the SCOM connection, which should be as short as distance as possible.

OPERATION:

The input operations of the terminal board include receiving signals from various sensors, encoders, and external switches. Feedback from encoders allows the system to monitor motor position and speed, ensuring accurate movement. The board also processes control inputs, such as start, stop, direction, and speed commands, which determine how the servo motor operates. Additionally, safety signals, including emergency stop (E-Stop) inputs, are handled by the board to immediately halt operations in case of a fault or hazardous condition.

DIAGNOSTICS:

• If the regulator feedback (LVDT) signal is out of limits, a fault is created and if the associated regulator has two sensors, the bad sensor is removed from the feedback calculation and the good sensor is used.

• If any one of the above signals goes unhealthy a composite diagnostic alarm, L#DIAG_VSVO, occurs. Details of the individual diagnostics are available from the toolbox. The diagnostic signals can be individually latched, and reset with the RESET_DIA signal if they go healthy.

• Connector JR1 on the terminal board has its own ID device that is interrogated by the I/O board. The ID device is a read-only chip coded with the terminal board serial number, board type, revision number, and connector location. When the chip is read by VSVO and a mismatch is encountered, a hardware incompatibility fault is created.

FREQUENTLY ASKED QUESTIONS:

How many inputs and outputs does it have?

The board features six input channels for LVDT position sensors and other signal inputs. Additionally, it has two servo output channels that provide control signals for servo motors. This configuration enables precise positioning and motion control in industrial applications.

How does the board handle servo coil currents?

The servo coil current can be adjusted between 10 to 120 mA using onboard jumper settings. This flexibility allows users to fine-tune the current levels to match the requirements of specific servo motors, ensuring optimal performance and efficiency.

What type of mounting does this board use?

The board is designed for DIN-rail mounting, making installation simple and efficient. A plastic holder is first mounted on the DIN rail, and then the board is slid into place, allowing for space-saving installation and easy maintenance.
