Description

The Honeywell 8U-TAOXB1 is a 16-channel analog output IOTA (Input/Output Termination Assembly) designed for integration into the Experion PKS Series C process control architecture. This red, uncoated module provides reliable 4-20 mA current output for a range of field devices, including control valves and actuators. Engineered for high-availability industrial environments, it supports online replacement, allowing for module insertion and removal without interrupting the control process.

Features

  • 16 isolated analog output channels supporting 4-20 mA signals.
  • Extended output range capability from 2.9 mA to 21.1 mA.
  • Redundancy-ready architecture with a maximum switchover gap of 10 ms.
  • Supports hot-swapping for enhanced system uptime and maintenance efficiency.
  • Optimized for low ripple and high-accuracy signal transmission in demanding process loops.

Applications

This module is frequently deployed in critical control applications such as chemical processing plants, thermal power stations, pharmaceutical manufacturing, refinery units, and offshore oil and gas platforms. It is specifically suited for distributed control systems (DCS) requiring precise actuator positioning and stable control loop performance.
