Honeywell MC-TAIL02 51304437-150 Analog Input

Product Overview

This analog input termination board provides a centralized wiring interface for field transmitters. It connects multiple analog sensors directly to Honeywell TDC 3000 input modules. The MC-TAIL02 51304437-150 organizes field cabling and simplifies maintenance tasks significantly. Its compact design reduces installation time and eliminates wiring errors in control cabinets. This board ensures reliable signal transmission from field devices to the control system.

Technical Specifications

The MC-TAIL02 51304437-150 measures 27.9 cm in height, 17.8 cm in depth, and 2.5 cm in width. It weighs approximately 0.75 kg, including all terminal blocks and mounting hardware. This board operates from the 24 VDC supply with a current draw of 100 mA typical. It provides sixteen discrete termination points for analog input signals from field transmitters. Each terminal accommodates wire sizes from 0.5 mm² to 2.5 mm² (20 to 14 AWG). The board includes built-in surge suppression for each channel to protect against transients. It also provides individual fusing for each input circuit to prevent overcurrent damage. The termination board connects to the main input module through a 50-pin ribbon cable. It features clearly numbered terminal positions for simplified wiring identification. The front panel includes LED indicators for power and channel activity monitoring.

Signal Routing and Protection Features

This board routes field signals to the appropriate input module with minimal signal degradation. It filters common-mode noise to ensure accurate measurement and reliable operation. The MC-TAIL02 51304437-150 includes reverse-polarity protection on each input channel. Users can disconnect individual channels without interrupting other inputs. The board also provides test points for troubleshooting each signal path.
