Physical Dimensions and Mounting

This module measures 125 mm in height, 45 mm in width, and 160 mm in depth. The unit weighs approximately 0.40 kg. It mounts directly onto a standard DIN rail within the Series C cabinet. The front panel includes 16 green LED indicators for per-channel activity. These LEDs illuminate when the corresponding input detects a valid signal.

Electrical Interface and Field Wiring

A 50-pin D-sub connector provides the primary interface for all field wiring connections. Each channel accepts either current or voltage signals through simple configuration jumpers. The module offers jumper-selectable input types for flexible deployment across applications. It also includes internal current loop power for 2-wire transmitters on each channel. This built-in power capability simplifies wiring and reduces external supply requirements. Field devices like pressure transmitters, thermocouples, and RTDs connect directly to these terminals.

Performance and Signal Processing

The MC-TAIH13 51309138-175 delivers 15-bit resolution for precise measurement of process variables. The module filters input signals to reject 50 Hz and 60 Hz noise effectively. It scans all 16 channels sequentially with a conversion time under 100 milliseconds. The analog-to-digital converter provides excellent linearity across the entire operating range. Moreover, the module performs automatic calibration checks to maintain long-term accuracy. The input circuitry includes overvoltage protection up to 30 VDC.

Installation and System Compatibility

You can install this module in any Honeywell TDC 3000 or Experion PKS system. The module occupies a single I/O slot in the Series C chassis configuration. The backplane automatically assigns addresses and handles all power distribution. Always select the correct input type using the onboard jumpers before energizing. For mission-critical measurements, use redundant modules to ensure continuous operation.

Environmental Certification

This module carries CE marking and UL recognition for global industrial deployment. It also complies with RoHS and WEEE sustainability directives. The conformal coating safeguards the PCB against moisture and airborne contaminants. This coating significantly improves reliability in demanding plant environments.
