It is designed to pair with two 440R‑EM4R2 expansion modules to realize MSR19E functionality in safety circuits. The module accepts power from 24 V AC\/DC or 120 V AC sources and supports the typical MSR19E load configurations, including DC loads up to 2 A at 24 V and AC loads up to 1.5 A at 120–250 V, with a thermal (non‑switching) load rating around 8 A. Common applications include machine guarding and safety interlock schemes in industrial automation, where additional safety outputs are required in conjunction with Guardmaster safety relays. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46250771972330,"sku":null,"price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-080.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-440r-zbe820az1-safety-expansion-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
