Allen-Bradley 700S-CF440DJC Safety Control Relay

Allen-Bradley 700S-CF440DJC Safety Control Relay is an eight-pole safety interposing relay from the 700S-CF family that provides a compact, dedicated safety path for machine controls. It uses a 24 VDC coil and mechanically linked, double-break contacts to improve safety interlock reliability and prevent welding of contacts. The eight poles deliver a mixed NO/NC contact arrangement, commonly implemented as 1 normally open, 3 normally closed, 3 normally open, and 1 normally closed across the poles, enabling complex safety logic for devices such as emergency-stop switches and safety interlocks. The unit is designed to be wired according to Rockwell Automation safety-circuit guidelines and typically uses input/safety wiring paths through the standard 700S-CF terminals for monitored reset and power signals. With its red faceplate and clearly identified 700S-CF interposing relay family design, the 700S-CF440DJC offers a straightforward upgrade path from basic relays to dedicated safety interlocks in control panels, without requiring a full safety PLC for many standard safeguarding applications. This model is suitable for applications that require rapid de-energization of a safety circuit in response to fault or hazard, helping to meet safety logic sequences in automated equipment.
