AutomationDirect RS4N-DE24VDC Relay Card Module

The AutomationDirect RS4N-DE is a four‑channel, plug‑in relay card that mounts in an in‑socket base for AutomationDirect’s RS‑series I/O systems. Each channel uses a 24 VDC coil Fuji Electric relay with four normally open contacts (4PST, (4) NO) and is rated for 5 A per channel, enabling independent switching of loads from a common 24 V control signal. The card features screw‑terminal wiring for reliable connections, finger‑safe construction, and ships with two jumpers and a TY3 relay remover for field servicing. Designed to fit a compact relay socket, the RS4N‑DE provides isolated outputs on a card‑level form factor, making it a straightforward load‑isolation and I/O expansion solution for PLC applications. Typical uses include actuating relays, solenoids, or other 24 VDC loads in machine controls and automation systems where four independent switching channels are required in a small footprint.
