ABB TEIP11 Electro-Pneumatic I/P Converter

Product Overview

The ABB TEIP11 delivers precise electrical-to-pneumatic signal conversion for demanding industrial automation systems. It supports accurate valve and actuator control by transforming standard 0/4–20 mA input signals into stable pneumatic output pressure. The compact design integrates easily into both new and legacy process installations, and the optional TEIP11-PS booster stage increases air capacity for large actuators. Moreover, its rugged construction ensures reliable performance in chemical plants, refineries, and power facilities where vibration, temperature extremes, and harsh field conditions are common.

Key Benefits

The TEIP11 provides consistent pressure output with excellent dynamic response, enabling smooth actuator movement. In addition, multiple housing options allow safe installation in control rooms or exposed outdoor environments. Operators appreciate its stable behavior under shock and vibration, while maintenance teams value the converter’s simple calibration method. The module also supports flexible mounting arrangements, which reduces integration time in retrofit projects.
