Description
1. Product Title
ABB FC-RUSIO-3224 – RUSIO Remote I/O Expansion Module for Freelance DCS System
2. Product Overview
The FC-RUSIO-3224 is a remote distributed input/output module tailored for Honeywell Freelance DCS distributed control systems. It expands the system’s field signal collection capacity by remotely deploying discrete digital signals away from the central controller cabinet, reducing lengthy field wiring complexity and lowering cable costs. This module processes 32-channel digital input and output signals, converts on-site switch status, relay feedback and interlock commands into bus-based digital data and transmits back to the Freelance AC 800F controller via standard fieldbus communication. Galvanic isolation circuits built into FC-RUSIO-3224 effectively block ground loop interference and voltage surges in harsh industrial environments, ensuring stable signal acquisition and reliable execution of process interlock, safety shutdown and sequential control logic for continuous production processes.
