ABB V18348-10111310110 TZIDC-200 Digital Positioner for Precision Valve Control

Product Overview

When precise valve positioning and reliable operation in hazardous environments are critical, the ABB V18348-10111310110 TZIDC-200 digital positioner delivers. This intelligent positioner features a flameproof enclosure certified ATEX Ex d II C T4/T5/T6 Gb, making it suitable for demanding industrial applications. It combines software-configurable control with a Local Communication Interface (LKS) and HART communication for seamless integration.

Key Technical Specifications

The V18348-10111310110 operates with a 4…20 mA signal range, minimum 4 mA and maximum 20 mA, freely selectable for split-range operation. It supports direct or reverse action, and offers linear, equal percentage (1:25, 1:50, 25:1, 50:1), or user-configurable characteristic curves with 20 reference points. The positioner includes a plug-in module for analog position feedback (4…20 mA, two-wire) and features an integrated operator panel with display. Connections include 1/2-14 NPT cable thread and 1/4-18 NPT air pipe thread.

Industry Applications

This digital positioner excels in oil and gas, chemical processing, and power generation where precise actuator control and safety are paramount. Its single-acting fail-safe output ensures the valve moves to a safe position upon electrical power failure. The ability to set travel limits, shut-off functions, and travel time prolongation allows customization for specific process requirements.

Installation and Setup Guidance

The V18348-10111310110 mounts to linear actuators per DIN/IEC 534/NAMUR or to rotary actuators per VDI/VDE 3845. The aluminium, varnished case provides durability. During setup, use the local operator panel or configuration software to adjust operating parameters such as signal range, action, characteristic curve, and travel limits. The automatic adjustment function simplifies parameter optimization.

Maintenance and Reliability

Routine inspection of the positioner and actuator is recommended to ensure consistent performance. The microprocessor-based control and high-precision functions contribute to operational reliability. Monitor diagnostic and maintenance parameters via the operator panel or HART communication to anticipate service needs.

Compatibility and Integration

The TZIDC-200 integrates with HART-enabled control systems. The digital input supports protective functions like move to 0% or 100% position, hold last position, or disable local configuration when the 24 V DC signal drops below 10 V DC. The digital output provides a collective alarm for system monitoring.

Selection and Purchasing Advice

Before ordering, verify that your actuator type and mounting interface match the NAMUR or VDI/VDE 3845 standards. The V18348-10111310110 is supplied new in factory packaging with a 12-month warranty. Contact BluePLC Industrial for current availability and lifecycle status.
