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.

Installation Guidelines

• Ensure the module is mounted securely within the Series C cabinet/rack environment.
• Verify that the power supply is stable at 24 VDC before energizing the IOTA.
• Handle with standard ESD precautions to prevent damage to internal circuitry.
• The module supports online insertion/removal; however, ensure all field wiring is properly terminated and verified before initiating control loops.
• Maintain proper airflow within the cabinet to ensure operating temperatures remain between 0-60 deg C.

FAQ

Is the 8U-TAOXB1 hot-swappable?
Yes, the hardware architecture is designed to support module insertion and removal under power, which minimizes process downtime during maintenance.

What is the typical redundancy switchover time?
The module is designed for a maximum output interruption gap of 10 ms during redundancy switchover events.
