10024/I/F | Honeywell FSC Enhanced Communication Module

Product Overview

The Honeywell 10024/F/F is an Enhanced Communication Module (ECM) for the Honeywell FSC (Fail Safe Control) system. It features dual Tri-state RS-232C interfaces on both Top (A) and Bottom (B) ports, designed for reliable point-to-point serial communication with external devices such as operator stations, printers, and DCS systems.

FAQ

Q: What does "tri-state" RS-232C mean?
A: Tri-state allows the interface to be electrically disconnected (high-impedance state) when not actively communicating, enabling safe bus sharing and redundant failover.

Q: Can both RS-232C interfaces connect to the same device?
A: Yes, both interfaces can connect to the same device for redundancy, with the FSC system automatically selecting the active path.

Installation Guide

1. Power down the FSC Central Part rack.
2. Remove system bus jumper before installation.
3. Insert the ECM into the Central Part slot (8 TE, 3 HE).
4. Connect RS-232C cables to Interface A and/or Interface B.
5. Configure baud rate and protocol via FSC software.

Selection Tips

• For dual RS-232C connections to operator stations and printers.
• For RS-485 network capability, consider 10024/I/I or 10024/I/F.
• For fiber optic communication, consider 10024/G/G.
