Description

ABB V18345-1020121001 TZIDC Electro-Pneumatic Positioner

Overview

ABB's V18345-1020121001 TZIDC Electro-Pneumatic Positioner is a communicating, electronically configurable positioner designed for mounting on linear or rotary actuators.

The V18345-1020121001 automatically determines control parameters and adapts the final control element, saving significant time. It can be installed on control valves with rotary actuators (using standard NAMUR mounting hardware) or linear control valves, and is available in a variety of configurations and functional options.

🚀Function & Features

I/P Converter + Pneumatic Amplifier: The V18345-1020121001 converts electrical signals into proportional pneumatic outputs for 3/3-way valves.

Four Pneumatic Modes: The V18345-1020121001 supports single-acting or double-acting actuators, fail-safe, and fail-freeze operation.

Built-in LCD Display and Keypad: The V18345-1020121001 features a dual-line LCD and four function keys for local configuration.

Operating costs: V18345-1020121001 has extremely low air consumption in steady state (e.g. < 0.03 kg/h/ 0.015 scfm, independent of supply pressure), reducing compressed air usage, and components (relays, fuses, current sensors, etc.) can be replaced in situ.

why choose us?

Our product has an extremely low gas consumption in steady-state (less than 0.03 kg/h). Compared to traditional positioners, the ABB V18345-1020121001 significantly reduces compressed air consumption. Equipped with an auto-tuning function, it only requires a one-touch start of the auto-tuning program after installation. It can automatically identify the actuator's dynamic characteristics and friction, and set the optimal control parameters.
