ABB V18345-1010120001 TZIDC Electro-Pneumatic Positioner – Reliable Valve Control

Product Overview

When precise valve positioning is critical in process control, the ABB V18345-1010120001 TZIDC Electro-Pneumatic Positioner delivers reliable performance. This intelligent positioner features an integrated indicator and operator panel for easy configuration and monitoring. Designed for demanding industrial environments, its aluminum housing with IP 65 (NEMA 4X) protection ensures durability against dust and moisture. The V18345-1010120001 supports both linear actuators per DIN/IEC 534/NAMUR and rotary actuators per VDI/VDE 3845, making it a versatile choice for a wide range of applications.

Technical Specifications

The V18345-1010120001 operates with a 4...20 mA two-wire input signal, providing a nominal output range of 4...20 mA. Its digital input accepts control voltages: 0...5 V DC for logical state "0" and 11...30 V DC for logical state "1". The digital output (per DIN 19234/NAMUR) has a supply voltage of 5...11 V DC. Supply pressure ranges from 1.4 to 6 bar (20 to 90 psi), with air consumption below 0.03 kg/h (0.015 scfm), independent of supply pressure. The unit weighs 1.7 kg and features pneumatic connections with threads G 1/4 or 1/4-18 NPT.

Industry Applications

This positioner excels in industries requiring accurate valve control, such as chemical processing, oil and gas, and water treatment. Its intelligent configuration allows split-range operation with signal ranges from 4 to 20 mA, freely selectable for minimum 20% range (3.2 mA) and recommended above 50% (8.0 mA). The characteristic curve can be linear, equal percentage (1:25, 1:50, 25:1, 50:1), or freely configurable with 20 reference points, adapting to diverse process needs.

Installation & Setup Guidance

Mounting the V18345-1010120001 is straightforward for both linear and rotary actuators. Ensure the housing is securely attached and the cable entry (1/2-14 NPT or M20 x 1.5) is properly sealed to maintain IP65 integrity. Electrical connections use screw terminals: max 1.0 mm² for options and max 2.5 mm² for analog signals. Avoid exposing terminals to strain. Pneumatic connections use G 1/4 or 1/4-18 NPT threads. During setup, configure the positioning signal action (increasing or decreasing) and set travel limits as needed, observing a minimum 20% travel range.

Maintenance & Reliability

Routine inspection of the V18345-1010120001 focuses on verifying proper operation and checking for any environmental stress. The unit operates reliably in ambient temperatures from -40 to 85 °C for operation, storage, and transport. When using proximity switches SJ2-S1N (NO), the temperature range is -25 to 85 °C. Relative humidity can reach 95% (annual average) with condensation permissible during operation, and 75% (non-condensing) for transport and storage. The electrostatic dipping varnish with epoxy resin (case black RAL 9005, cover Pantone 420) provides corrosion resistance. Regular testing according to manufacturer guidelines ensures long-term reliability.

Selection Guide & Purchasing Advice

Before ordering the ABB V18345-1010120001, verify that your application requires a single-acting, fail-safe positioner without explosion protection or optional feedback modules. This model includes a connector plug for LKS adapter and cable entry with 1/2-14 NPT thread. For additional options like analog or digital position feedback, consider other variants in the TZIDC series.
