Honeywell MU-TAIH22 80366195-100 Analog Input Module

This high-density analog input module captures process signals for Honeywell Experion PKS and TDC 3000 systems. The Honeywell MU-TAIH22 80366195-100 provides sixteen channels of 4-20 mA input with enhanced filtering for noisy field environments. Its compact form factor maximizes I/O density while maintaining measurement accuracy across challenging process conditions.

Key Technical Specifications

Input Architecture and High-Density Design

The Honeywell MU-TAIH22 80366195-100 provides sixteen input channels organized into four isolated groups of four channels each. This group isolation approach balances protection against common-mode voltages while optimizing space and cost. A 250 Ω input impedance ensures accurate current measurement from two-wire transmitters and sensors. The 150 ms scan rate provides adequate update speed for most process control applications while minimizing processing overhead.

Signal Conditioning and Filtering Performance

This analog input module incorporates robust filtering that attenuates high-frequency noise from variable speed drives and heavy electrical loads. Its 12-bit resolution delivers reliable measurements across the full 4-20 mA range with ±0.2 % accuracy at reference temperature. The ±75 ppm/°C temperature drift maintains stable readings despite ambient temperature fluctuations in control rooms. Furthermore, the module’s input protection withstands accidental overcurrent conditions up to 50 mA without permanent damage.

Mechanical Design and Rack Integration

The Honeywell MU-TAIH22 80366195-100 occupies a single slot in Experion PKS and TDC 3000 chassis with its 180 mm width and 230 mm height. Its 0.75 kg weight provides stable mechanical loading across the backplane connectors. A removable screw terminal block accepts 28 to 12 AWG field wires, simplifying cable terminations and maintenance activities. LED indicators on the faceplate display channel activity and module operational status.

Group Isolation and Noise Rejection

This input module provides 1,500 V AC isolation between each group of four channels and the system bus. Group isolation prevents ground loop disturbances from affecting measurement integrity in large installations. The module also filters out common-mode noise that could otherwise corrupt analog signals. Consequently, the Honeywell MU-TAIH22 80366195-100 maintains reliable readings even in electrically noisy industrial environments.

Power Consumption and Environmental Suitability

This module draws 95 mA from the 24 V DC backplane supply during normal operation. Its 0 °C to 60 °C operating range accommodates standard industrial process areas and control centers. An IP20 protection rating requires enclosure mounting but permits convenient front-panel access for wiring inspection. The module efficiently dissipates heat through its metal housing without forced-air cooling.

System Compatibility and Application Scope

The Honeywell MU-TAIH22 80366195-100 interfaces seamlessly with Experion PKS and TDC 3000 controllers for deterministic data acquisition. It integrates with Honeywell engineering tools for straightforward configuration and calibration. Consequently, this high-density analog module serves oil and gas production, chemical processing, power utilities, and wastewater treatment plants effectively.
