Honeywell TC-HAI081 Experion PKS 8-Channel HART Analog Input Module

Product Description

The TC-HAI081 is a high-performance analog acquisition interface designed for integration within Honeywell Experion PKS and compatible ControlLogix environments. This module features eight fully isolated input channels, providing the versatility to process standard voltage and current signals while supporting bi-directional HART (Highway Addressable Remote Transducer) digital communication. By enabling HART passthrough, it allows maintenance personnel to access advanced field device diagnostics and configuration data directly through the control system backplane.

Advanced Diagnostic Capabilities

The TC-HAI081 is specifically engineered for facilities utilizing smart field instrumentation. Beyond simply reading the 4-20 mA primary variable, this module extracts secondary and tertiary variables along with device status information via the HART protocol. The individual channel isolation is a critical feature, preventing ground loops and ensuring that an electrical fault on one instrument does not interfere with the data integrity of the remaining seven inputs.

Frequently Asked Questions

• Does this module support HART multi-drop configurations?

  The TC-HAI081 is primarily designed for point-to-point analog loops where each channel interfaces with a single smart transmitter to maintain high-speed update rates.

• Is external power required for the 4-20 mA loops?

  Depending on the field wiring and the specific chassis used, the TC-HAI081 can typically be configured to interface with both self-powered and loop-powered (2-wire) transmitters.
