Powered from 24 V AC\/DC, the module mounts on a 35 mm DIN rail and is 22.5 mm wide. The four safety outputs are rated up to 6 A at 250 V AC or 3 A at 24 V DC, with external fuses of 6 A slow-blow or 10 A quick-blow supported; contact material is AgSnO2 with a 0.5 µm gold alloy, and the unit features a 2500 V impulse withstand with IP40 enclosure protection. Operating temperature is -5 to 55 °C and up to 90% relative humidity, with copper conductors 0.2–2.5 mm2 and terminal screws torque 0.6–0.8 N·m. The ED variant provides a fixed 1-second delay per output and mirrors the host safety outputs, enabling reliable expansion of safety circuits for devices such as emergency stops, safety gates, and light curtains; the expansion mirrors the base state through a monitored feedback loop to maintain safety integrity. Typical power draw is around 3 W, and the module is designed for use alongside MSR safety bases to achieve additional channels without compromising safety in industrial automation. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46243454451946,"sku":null,"price":203.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-078.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-440r-e23193-minotaur-expansion-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
