Automation Direct RS4N-DE Card Relay

The RS4N-DE is a Fuji Electric card relay module offered by Automation Direct that packs four 24 VDC coil relays into a single in-socket, space-saving package. Each of the four relays provides a Form A (NO) contact with a 5 A rating, all configured as a 4PST block with screw-terminal connections and finger-safe housing for easy, secure wiring and safe handling. The kit includes four relays, a TY3 relay remover, and two jumpers, simplifying installation and replacement in a control panel. With 24 VDC coil voltage, this in-socket card is designed to interface standard automation controllers with external loads while keeping wiring tidy and minimizing panel depth. Typical applications include expanding a control system’s output capability to drive external devices such as solenoids, indicators, or small actuators across four independent channels, all from a compact, plug-in module. Each channel is rated for up to 5 A, enabling practical switching for common automation tasks without needing separate relays for every output.
