4-20 mA HART Process Signal Interface

The Honeywell TK-IAH161 processes standard 4-20 mA field signals from smart transmitters and provides HART communication capability for digital device information exchange. The module supports simultaneous analog measurement and HART data access, allowing configuration parameters, diagnostics, and secondary variables to be transferred through the same field loop.

Moreover, the module applies channel-to-channel isolation techniques to reduce electrical interference between independent measurement circuits. The input architecture supports connection with process transmitters including pressure, temperature, flow, and level instruments within Experion PKS control environments.
