ABB V18345-1010121001 Electro-Pneumatic Positioner

The ABB V18345-1010121001 is a TZIDC series electro-pneumatic positioner designed for precise control of pneumatic actuators in industrial process applications. It converts a 4-20mA electrical control signal into pneumatic output to accurately position valves, dampers, and other final control elements. This model features single-acting operation with fail-safe functionality and HART communication capability.

Key Features

• Intelligent Control:​ Microprocessor-based with auto-tuning capabilities for optimal performance.

• HART Communication:​ 4-20mA two-wire input with HART protocol for configuration and diagnostics.

• Fail-Safe Operation:​ Single-acting with fail-safe reset function for safety-critical applications.

• Robust Construction:​ IP65-rated aluminum housing suitable for industrial environments.

• Versatile Mounting:​ Compatible with both linear and rotary actuators.

Important Selection & Installation Notes

1. Actuator Compatibility:​ Verify that the positioner is compatible with your specific actuator type (linear or rotary) and mounting interface.

2. Supply Air Quality:​ Requires clean, dry compressed air (ISO 8573-1:2010 [7:4:4] or better) to ensure reliable operation.

3. Configuration Required:​ The positioner requires configuration (characteristic curve, fail-safe mode, etc.) using a HART communicator or ABB configuration software before commissioning.

4. Wiring:​ Use shielded twisted-pair cable for the 4-20mA signal to minimize electrical noise interference.

5. Calibration:​ Periodic calibration is recommended for critical applications to maintain positioning accuracy.
