SICK UE410-SD400 Relay

UE410-SD400 is a Safeguard Detector safety evaluation module from SICK, part number 1088689, designed to monitor one or two MultiPulse sensor pairs and deliver a safe signal to the actuator directly from the UE410-SD unit. It operates from a 24 V DC supply (19.2–30 V), with a Class III (EN 50178) power class and IP20 protection, and is rated for -25 °C to 55 °C. The device uses hard-wired configuration and spring-terminal connections and supports one or two sensor pairs for flexible safety layouts; the total system response time (sensors plus module) is ≤ 160 ms. Certifications include EU and UK conformity, ACMA, China RoHS, UK-Type-Ex, and cULus, reflecting broad regulatory compliance. The UE410-SD400 can be integrated into safety chains and expanded with additional logic elements to accommodate higher-level safety controllers, making it suitable for safeguarding material-handling conveyors and automated equipment where dependable safety evaluation is required.
