🔹 Product Description

The GE General Electric IS210DSVOH1A is a DSVO Compact Servo Terminal Board designed for the GE Mark VI Speedtronic turbine control system. It provides two servo valve outputs, six LVDT position-sensor inputs, and two active pulse-rate inputs for flow measurement. The board supports jumper-selectable servo coil currents from 10 to 120 mA and connects to the VSVO processor through a 37-pin cable. The IS210DSVOH1AA designation identifies the associated simplex DIN-rail terminal assembly, while IS200DSVOH1ABA is the related Servo I/O Terminal Board assembly. The DSVO assembly uses Euro-block terminals and is intended for simplex servo-control applications.

🔹 Frequently Asked Questions

Q1: What is the IS210DSVOH1A used for?
The IS210DSVOH1A is a Compact Servo Terminal Board used to interface servo valves, LVDT position sensors, and active pulse-rate signals with the GE Mark VI control system.

Q2: How many servo valve outputs are available?
The DSVO terminal board provides two servo valve outputs.

Q3: How many LVDT inputs does the board provide?
The IS210DSVOH1A provides six LVDT position-sensor inputs.

Q4: What is the function of the pulse-rate inputs?
The two active pulse-rate inputs can be used for flow measurement within the turbine control application.

Q5: What is the servo coil current range?
The servo coil current is jumper selectable from approximately 10 to 120 mA. The actual setting should match the connected servo valve and system configuration.

Q6: What is the relationship between IS210DSVOH1A and IS210DSVOH1AA?
IS210DSVOH1A identifies the Compact Servo Terminal Board, while IS210DSVOH1AA identifies the simplex DIN-rail mounted servo terminal assembly. They belong to the same DSVO hardware family but should not be treated as interchangeable without confirming the system configuration.

Q7: What is IS200DSVOH1ABA?
IS200DSVOH1ABA is a related Servo I/O Terminal Board assembly in the Mark VI DSVO family. The complete part number and revision should be compared with the existing hardware before replacement.

Q8: Is this a simplex or TMR board?
The IS210DSVOH1AA version is documented as a simplex DIN-rail mounted terminal board. Verify the exact assembly designation before installation.
