ABB V18347-2041150001 TZIDC-120 Electro-Pneumatic Positioner for FOUNDATION Fieldbus

Introduction

This intelligent positioner uses FOUNDATION Fieldbus communication for seamless integration into modern distributed control systems. Its rugged aluminum housing withstands harsh industrial conditions while providing accurate actuator control.

Technical Specifications Breakdown

The V18347-2041150001 features a model code V18347 - TZIDC-120 Electro-Pneumatic Positioner, designed for FOUNDATION Fieldbus communication. This intelligent unit includes an indicator and operator panel for local configuration. The case is made of varnished aluminum with a mechanical position indicator, supporting mounting to linear actuators per DIN/IEC 534/NAMUR or rotary actuators per VDI/VDE 3845. Explosion protection meets ATEX EEx ia IIC T6, making it suitable for Zone 1 hazardous areas. The output configuration is single acting, fail-safe, ensuring the valve moves to a safe position upon power loss. Connections include cable thread M20 x 1.5 and air pipe thread 1/4-18 NPT. The unit weighs 1.7 kg and offers IP65 / NEMA 4X protection.

Industry Applications

In oil and gas refineries, the ABB V18347-2041150001 positions control valves on feed lines, maintaining precise flow despite temperature extremes from -40 °C to +85 °C. Chemical plants benefit from its ATEX EEx ia IIC T6 certification, allowing installation in explosive atmospheres. The FOUNDATION Fieldbus interface enables easy integration with existing DCS systems, reducing wiring and commissioning time.

Installation & Setup Guidance

Mount the positioner directly to the actuator using the provided bracket. Connect the air supply to the 1/4-18 NPT air pipe port. For electrical connections, use the M20 x 1.5 cable gland with screw terminals rated for max 2.5 mm² analog signal wires. Ensure the housing is closed and sealed to maintain IP65 protection. Configure the unit via the operator panel or FOUNDATION Fieldbus host.

Maintenance & Reliability

The aluminum case with electrostatic dipping varnish resists corrosion in humid environments. The unit operates reliably in 95% relative humidity (condensation permissible) with air supply on. For transport and storage, keep humidity below 75% non-condensing. Periodic inspection of cable glands and pneumatic connections ensures long service life.

Compatibility & Integration

This positioner communicates via FOUNDATION Fieldbus, making it compatible with any host system supporting this protocol. It works with linear actuators per DIN/IEC 534/NAMUR and rotary actuators per VDI/VDE 3845. The single-acting fail-safe output suits spring-return actuators.

Selection Guide & Purchasing Advice

Before ordering the V18347-2041150001, verify your actuator type and mounting requirements. Confirm that your control system supports FOUNDATION Fieldbus. For applications requiring shutdown modules or digital position feedback, consider alternative configurations. AutoDCSTech stocks this model and can advise on availability and lifecycle status.
