GE IS210MVRAH2A

¥999.00

The GE IS210MVRAH2A is a VMEbus terminal board manufactured by General Electric for the Mark VIe distributed control system (DCS). This board is a dedicated Motorized Valve and Regulator Actuator Control module, designed to provide precise control of motor-operated valves (MOVs), regulators, and electric actuators in turbine and industrial control applications. The GE IS210MVRAH2A converts digital control signals from the processor board (VPRO series) into motor drive outputs, enabling accurate positioning of motorized valves for fuel, steam, and process control. The “H2A” designation indicates a second-generation motorized valve and regulator actuator control module with enhanced performance and reliability.

Selection Guidelines

  • When to choose: Applications requiring precise control of motor-operated valves and electric actuators.

  • Motor Selection: Verify motor voltage (24 VDC), current (≤2 A continuous, ≤4 A inrush).

  • Position Feedback: Select feedback type (4–20 mA, 0–10 V, or potentiometer) per channel.

  • Control Mode: Select position control for precise positioning; speed control for smooth operation; torque control for constant force.

  • Soft-Start Configuration: Set acceleration/deceleration rates to minimize mechanical shock.

  • Valve Diagnostics: Configure stall detection thresholds and end-of-travel limits.

  • Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.0 or higher.

Operational Precautions

  1. Wiring: Follow GE wiring diagrams—correct polarity for motor and feedback connections.

  2. Motor Power: Provide dedicated 24 VDC motor power supply with capacity for all motors.

  3. Position Feedback Verification: Verify feedback signal matches valve position during commissioning.

  4. Soft-Start Testing: Perform full-stroke tests to verify acceleration/deceleration settings.

  5. Stall Detection Testing: Simulate stall condition to verify diagnostics and protection.

  6. LED Diagnostics: Green = normal; Amber = fault; Red = motor fault/stall.

  7. Fault Log: Access 500-event log via Toolbox ST.

  8. Hot-Swap: Remove/insert slowly under power.

  9. Spare Stock: Maintain 1 spare per 3–4 racks.

  10. Firmware Updates: Ensure the GE IS210MVRAH2A is in “standby” mode during updates.

  11. ESD: Handle by edges with grounded wrist strap.
