Honeywell 51304337-100 MU-TAIH12 Analog Input Board

This high-density analog input board captures process signals from field transmitters in Honeywell distributed control systems. The Honeywell 51304337-100 MU-TAIH12 provides sixteen channels of 4-20 mA input with robust filtering for electrically noisy environments. Its compact form factor maximizes I/O density while maintaining measurement accuracy for critical process variables.

Key Technical Specifications

Input Architecture and Group Isolation

The Honeywell 51304337-100 MU-TAIH12 organizes its sixteen input channels into four isolated groups of four channels each. This group isolation approach provides effective protection against common-mode voltages while optimizing board space and cost. A precision 250 Ω resistor ensures accurate current-to-voltage conversion for standard 4-20 mA loop-powered transmitters. The 120 ms scan rate delivers adequate update speeds for most process monitoring and control applications.

Signal Conditioning and Measurement Accuracy

This analog input board incorporates robust filtering that attenuates high-frequency noise from variable speed drives and heavy switching loads. Its 12-bit resolution delivers reliable measurements across the full 4-20 mA range with ±0.15 % accuracy at reference temperature. The ±50 ppm/°C temperature drift maintains stable readings despite ambient temperature fluctuations in control rooms. Moreover, the board’s input protection withstands accidental overcurrent conditions without permanent damage.

Mechanical Design and Rack Integration

The Honeywell 51304337-100 MU-TAIH12 occupies a single slot in Experion PKS and TDC 3000 chassis with its 180 mm width and 230 mm height. Its 0.74 kg weight provides stable mechanical loading across backplane connectors. A removable screw terminal block accepts 28 to 12 AWG field wires, simplifying cable terminations and future modifications.

Group Isolation and Noise Rejection Performance

This input board provides 1,500 V AC isolation between each group of four channels and the system bus. Group isolation prevents ground potential differences from affecting measurement integrity in large distributed installations. The module also filters out common-mode noise that could otherwise corrupt analog signals. Consequently, the Honeywell 51304337-100 MU-TAIH12 maintains reliable readings even in electrically harsh industrial environments.

Power Consumption and Environmental Tolerance

This analog input board draws 90 mA from the 24 V DC backplane supply during normal operation. Its 0 °C to 60 °C operating range accommodates standard process control areas and control centers. An IP20 protection rating requires enclosure mounting but permits convenient front-panel access for wiring inspection. The board efficiently dissipates heat through its metal housing without forced-air cooling.

System Compatibility and Application Scope

The Honeywell 51304337-100 MU-TAIH12 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 board serves oil and gas facilities, chemical plants, power utilities, and water treatment systems effectively.
