FC-DCOM-234/485 Honeywell Communication Interface Module

Product Description

The Honeywell FC-DCOM-234/485 is a communication interface module that provides RS232 and RS485/422 serial communication options for industrial control systems. It supports different baud-rate ranges across the two interfaces, allowing connected equipment to exchange serial data at rates suited to the selected communication mode. The module operates from a 5 VDC supply provided by the control processor(s) and supports DIN rail mounting.

Key Features

• Dual serial interfaces: Provides RS232 and RS485/422 communication options.
• Flexible baud rates: Supports up to 250 kBaud on RS232 and up to 2 MBaud on RS485/422.
• Multiple encoding modes: RS485/422 communication supports transparent, FM0, FM1, or Manchester-coded operation.
• DIN rail mounting: Includes a snap-in provision for TS32 and TS35 rails in accordance with EN standards.
• Conformal coating: Provides a protective coating for the module's electronic assembly.

Technical Specifications

Serial Communication and Integration

The RS232 and RS485/422 interfaces support different serial communication requirements. RS232 operates at baud rates up to 250 kBaud, while RS485/422 supports rates up to 2 MBaud and the listed encoding modes. Confirm the required electrical interface, baud rate, and communication format against the connected device before selecting the module.

The module receives its 5 VDC supply from the control processor(s), with a maximum input current of 500 mA. This supply arrangement should be considered when checking the control system's power capacity and the module's installation requirements.

Frequently Asked Questions

Q: What communication interfaces does the FC-DCOM-234/485 provide?
