Honeywell MC-TDPR02 Digital Input Module

Product Overview

The Honeywell MC-TDPR02 delivers high-density digital input processing for distributed control systems. This module handles 32 discrete channels and operates with a nominal 24 VDC supply voltage. It provides reliable signal acquisition from field devices like proximity sensors and selector switches. The unit fits seamlessly into Honeywell Series C I/O chassis.

Technical Specifications

Physical Dimensions and Mounting

This module measures 125 mm in height, 45 mm in width, and 160 mm in depth. The unit weighs approximately 0.42 kg. It mounts directly onto a standard DIN rail inside the Series C cabinet. The front face includes 32 LED indicators that show each channel’s on/off status. These LEDs facilitate quick diagnostics and system verification during commissioning.

Electrical Interface and Field Wiring

A 50-pin D-sub connector provides the primary interface for field wiring termination. This connector supports both sinking and sourcing input configurations. Each input channel includes surge suppression circuitry to handle transient voltages. The module draws its operating power exclusively from the backplane connection. Typical power consumption stays below 7 W under full operational load.

Performance and Response Characteristics

The MC-TDPR02 scans all 32 input channels within a single control cycle period. This scanning method ensures deterministic response times for time-critical processes. The optical isolation barrier withstands 1500 VAC during dielectric strength testing. Built-in diagnostic functions monitor each channel for open-circuit or short-circuit conditions. The module reports any detected faults directly to the main controller. Consequently, this feature enhances overall system availability and reduces downtime.

Installation and System Integration

This input module integrates seamlessly with Honeywell TDC 3000 and Experion PKS platforms. You can place the module in any available I/O slot within the Series C chassis. The backplane automatically handles address assignment and power distribution tasks. For critical applications, you can implement redundant modules for hot-standby operation. Always confirm that the firmware revision matches your system requirements before installation.

Environmental Compliance and Certification

This module carries CE marking and UL certification for global industrial deployment. It also complies with RoHS and WEEE environmental directives. The conformal coating on the PCB protects against moisture and airborne contaminants. This coating extends the module’s operational life in challenging plant environments.
