Honeywell TK-HAO081 8 Channel Analog Output Module

The Honeywell TK-HAO081 is a high-performance 8-channel analog output module, specifically designed for Honeywell’s Experion Process Knowledge System (PKS) and TDC 3000 platforms. This module is responsible for converting control signals from the system controller into analog outputs that can be used to drive field devices such as control valves, actuators, and dampers.

Each of the eight output channels is independently configurable for current (4–20 mA) or voltage (0–10 V) output, offering flexible signal control for a wide range of industrial applications. It features 16-bit resolution, enabling precise and repeatable control across all outputs. The TK-HAO081 is equipped with advanced diagnostics, overload protection, and hot-swap capabilities, ensuring both reliability and maintainability in mission-critical environments.

Whether in oil and gas, energy, chemical, or water treatment facilities, the TK-HAO081 ensures robust, real-time analog control and smooth integration into larger distributed control systems.
