More Information

Overview Manuals Applications Temperature Installation Diagnostics

Features:

  • Provides sixteen fully isolated low-level thermocouple input channels.
  • Accepts eight documented thermocouple standards through a -20 to +100 mV input path.
  • Operates from a nominal 24 VDC supply with a fixed one-second input update.
The requested ordering identity combines the MC-TAMT04 designation with part number 51305890-175 for the Honeywell TPS low-level analog multiplexer termination assembly.

Its sixteen-channel layout organizes multiple process-temperature inputs while maintaining electrical separation across the measurement paths and Process Manager interface.

Confirm the sensor standard, channel assignment, supply range and cabinet environment before transferring field conductors or installing a replacement assembly.

Availability is confirmed against the complete ordering identity, required condition, quantity and delivery destination at quotation.

  • Collect multiple thermocouple measurements in Honeywell TPS Process Manager cabinets.
  • Serve furnace, reactor and utility temperature points with slowly changing thermal signals.
  • Maintain isolated channel routing where separation from the Process Manager and supply common is required.
  • The documented operating range is 0 to +50 °C for normal service.
  • Storage conditions may extend from -40 to +80 °C when the assembly is not energized.
  • Relative humidity is limited to 10-90% non-condensing, with 40 °C as the stated maximum temperature at that humidity range.
  • Apply a nominal 24 VDC supply and remain within the documented 15-30 VDC operating range.
  • Allow for 160 mA supply demand at 15 VDC and 2.25 W maximum internal dissipation.
  • Preserve channel numbering and isolation boundaries when reconnecting the sixteen input circuits.
  • A fixed one-second input update sets the expected response timing during channel checks.
  • The 0 to 4.7 Hz bandwidth should be considered when evaluating simulated temperature changes.
  • Separate sensor-type or polarity errors from channel-isolation and Process Manager interface faults.
Description
MC-TAMT04 51305890-175 provides sixteen isolated low-level input channels for Honeywell TPS Process Manager thermocouple measurement. The field termination assembly accepts J, K, E, T, B, S, R and Japan Type R′ sensors while maintaining separation between channels, the Process Manager interface and the power-supply common.

The input path handles −20 to +100 mV signals with a fixed one-second scan interval and a 0 to 4.7 Hz bandwidth. This combination is suited to process-temperature points where stable multiplexed acquisition matters more than high-speed response, including furnaces, reactors, utilities and other slowly changing thermal duties.

A 24 VDC nominal supply powers the assembly across the documented 15–30 VDC range, with 160 mA consumption at 15 VDC and 2.25 W maximum dissipation. Installation planning should preserve channel isolation, confirm the selected thermocouple standard and observe the stated ambient and humidity limits before energizing the replacement.

Technical notes
MC-TAMT04 51305890-175 requires verified thermocouple type, polarity and channel mapping before reconnection. Do not defeat the documented channel-to-channel, Process Manager or supply-common isolation boundaries during testing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is Honeywell MC-TAMT04 51305890-175 suited to multiplexed process-temperature measurement?
Its sixteen fully isolated low-level channels combine broad thermocouple support with a one-second acquisition cycle, matching slowly changing industrial temperature signals.
How should mixed thermocouple populations be planned around Honeywell MC-TAMT04 51305890-175?
Document each assigned sensor standard and polarity before termination so J, K, E, T, B, S, R or Japan Type R′ inputs remain correctly mapped to the control database.
What cabinet power review is needed before installing Honeywell MC-TAMT04 51305890-175?
Confirm that the available DC source remains inside the specified operating window and can cover the assembly’s stated current demand and heat dissipation.
How can technicians distinguish signal delay from a fault on Honeywell MC-TAMT04 51305890-175?
Allow for the fixed input-update period and low-frequency channel bandwidth when applying a simulator; a change that appears slowly may be normal measurement-path behavior.
Which environmental check matters when stocking Honeywell MC-TAMT04 51305890-175 for a shutdown?
Verify that storage temperature and condensation control remain within the documented limits, then inspect terminals and isolation surfaces before cabinet installation.
What information should accompany a Honeywell MC-TAMT04 51305890-175 quotation request?
Include clear nameplate images, required quantity, thermocouple standards, cabinet supply details, destination and any inspection or test documentation needed for acceptance.
