Frequently Asked Questions

• What is the difference between FC and FS versions? Both share core electrical and mechanical specs. The prefix may denote different product families or packaging within Honeywell's safety system portfolio.
• How many devices can it control? It has 10 independent relay output channels to control up to 10 separate field devices.
• What types of loads can it switch? It can switch both AC (up to 48VAC) and DC (up to 48VDC) loads such as small motors, lamps, solenoids, and alarm horns, within its power rating.
• What is the advantage of gold-flush contacts? Gold-flush contacts resist oxidation, ensure a stable low contact resistance over time, and are suitable for low-current switching, enhancing long-term reliability.
• What is Overvoltage Category 3? It indicates the module is designed for equipment in fixed installations (e.g., distribution panels) where transient overvoltages can be higher than in household environments (Category 2).
