Introduction

The Honeywell 2MLF-RD8A RTD Input Module is a professional-grade 8-channel temperature sensing module engineered for precise and reliable RTD-based temperature measurements in industrial automation systems. Designed for seamless integration with Honeywell MasterLogic‑200 (ML200 / ML200R) controller families and other compatible DCS/PLC systems, it ensures real-time, stable acquisition of temperature data. Ideal for process control, plant monitoring, and environmental regulation, this module delivers robust performance under demanding industrial conditions.

Technical Specifications

Parameter Details
Input Channels 8 independent RTD input channels
Supported Sensor Types PT100 standard; optionally PT1000 or other RTDs depending on configuration
Temperature Measurement Range –200 °C to +850 °C for PT100 sensors
Conversion / Sampling Speed ~40 ms per channel
Digital Output / Scaling Digital value output (e.g., 0–65535 or –32768 to 32767) for mapped temperature scaling
Accuracy / Precision Typical: ±0.2% at 25 °C; full-scale range: ~±0.3% (0–55 °C), depending on conditions and sensor accuracy
Wiring Method 3‑wire RTD standard; may support 2‑wire or 4‑wire depending on design
Isolation Terminal-to-PLC power isolation via photo‑coupler; no per-channel isolation specified
Form Factor / Mounting Rack-mount module for Honeywell ML200 / control system backplane
Weight Approx. 0.12 kg
Other Notes Supports digital scaling and user-defined temperature mapping; suitable for industrial temperature sensing tasks

Applications

  • Temperature monitoring and control in chemical, petrochemical, and process plants.

  • Industrial furnace, kiln, oven or heating system temperature measurement.

  • HVAC systems and building automation requiring multiple RTD sensors.

  • Power generation and utilities for monitoring equipment and environmental control.

  • Water treatment, wastewater, and environmental control applications where accurate temperature data is critical.

  • Retrofitting or expanding RTD‑based sensing capability in existing Honeywell ML200 / DCS systems without major redesign.

Advantages

  • Eight independent inputs — allows you to monitor multiple locations or devices with a single module, saving rack space and simplifying wiring.

  • Wide measurement range — from –200 °C up to +850 °C (with the right RTD), covering a broad spectrum of industrial temperature sensing needs.

  • Fast conversion per channel (~40 ms) — supports relatively frequent sampling, useful in dynamic or time-critical processes.

  • Good overall accuracy and stability — suitable for process control environments where temperature precision matters.

  • Compact, rack‑mountable design — integrates cleanly into standard Honeywell ML200 / PLC backplanes, simplifying system architecture.

  • Scalable and flexible — adds RTD capability to systems without needing dedicated transmitters or extra hardware; ideal for system expansion or upgrades.

  1. Q: How many RTD sensors can the 2MLF‑RD8A handle?
    A: Up to 8 independent RTD input channels.

  2. Q: What RTD types are supported?
    A: Typically PT100; optionally PT1000 or other RTD types depending on system configuration.

  3. Q: What is the temperature measurement range?
    A: –200 °C to +850 °C for PT100 sensors.

  4. Q: What is the response/conversion speed per channel?
    A: Approximately 40 ms per channel.

  5. Q: What is the expected accuracy?
    A: Around ±0.2% at 25 °C; over the typical operating range (0–55 °C), accuracy is roughly ±0.3%.

  6. Q: What wiring method is used for RTDs?
    A: 3‑wire configuration is standard; 2‑wire or 4‑wire may also be supported depending on system setup.

  7. Q: Does the module provide isolation between inputs and control logic?
    A: Yes — terminal-to-PLC power is isolated via photo‑coupler; RTD inputs are not isolated channel-to-channel.

  8. Q: Can this module be integrated into an existing Honeywell ML200 system?
    A: Yes — it is designed for plug-in rack-mount integration with ML200 / ML200R controllers.

  9. Q: Is the module suitable for high-temperature industrial environments?
    A: Yes — with appropriate RTD sensors rated for high temperatures (up to +850 °C), the module supports a wide range of industrial applications.

  10. Q: Does the module output digital scaled values for temperature?
    A: Yes — it provides digital output values (e.g., 0–65535 or –32768 to 32767) for mapping to real-world temperature values through configuration.
