The Honeywell FC-RO-1024 Relay Output Module is a high-performance output module designed to provide reliable relay-based switching control for industrial automation systems. It belongs to the Honeywell control platform family and is used to interface process controllers with field devices such as motors, solenoids, alarms, and actuators.

Built with robust electromechanical relays, the module ensures safe and accurate actuation of connected devices. It offers high isolation between the control system and field wiring, reducing the risk of electrical interference. Its modular architecture makes it suitable for integration into Honeywell’s distributed control systems (DCS) and programmable automation controllers (PACs).

This module is widely applied in industries where robust switching, signal integrity, and operational safety are critical, including power generation, petrochemicals, oil and gas, water treatment, and discrete manufacturing.
