Weidmüller 9443100000 Solid-State Relay

The Weidmüller 9443100000 solid-state relay is an industrial DIN rail mounted SSR (model RSO 30/DV 5-24V CC/SC) designed to interface DC control signals with DC loads in PLC cabinets, process control systems, and automation panels where fast, wear-free switching and electrical isolation are required.

Key specifications include SPST-NO (1 Form A) contact configuration, 5-24VDC ±20% control voltage, 2-60VDC switching voltage, 3A continuous current, 5mA DC control current, and switching frequencies up to 500 Hz. Turn-on delay is <300 µs and turn-off delay is <1 ms, with a voltage drop at max load of 1.6 V and leakage current ≤1 mA. The unit mounts on TS35 DIN rails and uses screw terminals, featuring a free-wheeling diode and galvanic isolation. It carries IP20 protection and operates from -25°C to +40°C, with a width of 11 mm.

Applications span industrial DC signal switching and isolation in PLC cabinets, packaging machinery, OEM manufacturing equipment, robotic systems, and process automation panels requiring rapid switching and reliable isolation. The 9443100000 is discontinued, with a replacement available under part number 2773730000; common substitutes include Weidmüller 2773730000, Phoenix Contact solid-state relays, and Omron G3 Series SSRs.
