Product Overview

The Honeywell FC-DCOM-232/485 acts as a high-integrity serial communication bridge for Honeywell Safety Manager and Experion PKS systems. This module provides essential connectivity between safety-critical controllers and external subsystems, third-party PLCs, or field instrumentation. By supporting both RS-232 and RS-485 standards, it facilitates seamless data exchange across diverse industrial protocols. We supply this module as 100% Brand New and Original, ensuring your safety system maintains laboratory-grade communication stability in the most demanding process environments.

Technical Specifications

Engineering Advantages

• Multi-Protocol Versatility: The FC-DCOM-232/485 eliminates the need for multiple converter modules by integrating one RS-232 port and two RS-485 ports into a single unit. This allows for simultaneous communication with different device classes, such as HMIs and long-distance sensor networks.

• Deterministic Data Integrity: Engineered for safety-critical integration, the module executes precise data packet management. It ensures that critical diagnostic information from third-party equipment reaches the Safety Manager CPU without latency or signal degradation.

• Rugged Thermal Endurance: The module withstands extreme temperatures ranging from -40°C to +70°C. This durability makes it ideal for remote instrument enclosures (RIE) located in harsh climates, ensuring the communication link remains active even during environmental spikes.

• Redundancy-Ready Architecture: Designed to support high-availability systems, the module integrates into redundant communication paths. This architecture prevents a single serial cable fault from blinding the Safety Manager to its external subsystems.

• Compact Modular Footprint: The lightweight, 0.99 lb design snaps into standard Honeywell Safety Manager racks. Its efficient use of space allows for increased I/O and communication density within the control cabinet.

FAQs

Does the FC-DCOM-232/485 support simultaneous RS-232 and RS-485 operation?

Yes. The module provides one RS-232 port and two RS-485 ports that operate independently, allowing you to bridge different physical layers within a single communication node.

Can I use this module for SIL-rated safety functions?

The FC-DCOM-232/485 carries SIL-rated certification, making it suitable for use within a Safety Instrumented System (SIS). It maintains the integrity required for transmitting data between the safety controller and external devices.

What is the required input voltage for the module?

The module operates on a 5 VDC internal logic bus but is compatible with standard 24 VDC Honeywell power distribution systems within the rack. It draws approximately 500mA during full communication load.

Is this unit a refurbished or "surplus" part?

No. We guarantee that this unit is 100% Brand New and Original. It ships in its original factory packing and includes a 12-month warranty, ensuring you receive a current-revision module with full manufacturer reliability.
