Product Description

The FC-DCOM-234/485 is a high-speed serial communication interface module for the Honeywell Safety Manager system. It provides a reliable bridge between internal processor signals and industry-standard serial protocols, including RS232, RS485, and RS422, enabling seamless integration with Distributed Control Systems (DCS), Human-Machine Interfaces (HMI), and third-party PLCs.

Equipped with dual communication ports, the module supports transparent data transmission as well as specialized coding schemes such as Manchester, FM0, and FM1. Designed for industrial longevity, it features a conformal-coated PCB to resist moisture, dust, and corrosive environments. Its snap-on DIN-rail mounting allows quick installation in standard control cabinets, providing a SIL-rated pathway for safety-critical communication.

Technical FAQ

Does this module require an external power supply?
No. The FC-DCOM-234/485 draws 5 VDC directly from the Honeywell Control Processor, simplifying cabinet power wiring.

Can it be used for Modbus communication?
Yes. While it functions as a physical-layer converter, it is commonly deployed to facilitate Modbus RTU or other serial protocols between the Safety Manager and external hardware.
