FCL Components offers a full range of relays designed for use in interface relay modules—critical components that bridge low?power control electronics with high?power industrial loads. Integrated into compact DIN?rail housings, these relays provide the essential functions required in modern automation environments.

Our JS, FTR?MY, FTR?LY, NY, and FTR?K1?HT relay series support the four core roles of interface relays: galvanic isolation, signal amplification, voltage conversion, and signal multiplication. This enables PLCs and controllers to safely operate motors, conveyors, pumps, lighting circuits, HVAC equipment, and other high?demand loads.

These relays are widely used across industrial automation, building management systems, power and energy infrastructure, transportation equipment, and medical devices. They deliver stable switching performance even under frequent cycling, high inrush currents, and varying temperatures.

FCL relays provide key benefits such as noise suppression, long operational life, and robust isolation—ensuring reliable operation and protection for sensitive control electronics in demanding environments.
