Designed for machine safety applications, it provides flexible safety control architecture while minimizing panel space. Although this model includes no safety outputs, it provides three normally open (N.O.) solid-state auxiliary outputs and can be expanded with additional safety and output modules depending on the safety circuit design. Its monitored automatic\/manual reset function supports enhanced operator and system diagnostics. The 35 mm housing width supports efficient DIN rail mounting, and the RS-232 communication port allows configuration or diagnostics when required. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eApplication: Modular safety relay base for configurable safety systems.\u003c\/li\u003e\n\u003cli\u003eVoltage: Operates at 24 VDC for standard low-voltage industrial environments.\u003c\/li\u003e\n\u003cli\u003eOutput Configuration: 0 safety outputs, 3 N.O. auxiliary solid-state outputs.\u003c\/li\u003e\n\u003cli\u003eReset Type: Supports both automatic and manual monitored reset modes.\u003c\/li\u003e\n\u003cli\u003eEnclosure Size: Compact 35 mm housing for efficient DIN rail mounting.\u003c\/li\u003e\n\u003cli\u003eConnectivity: Includes RS-232 interface for optional diagnostics\/configuration.\u003c\/li\u003e\n\u003cli\u003eCompliance: Certified to CCC, CE, CUL, and UL standards for global application.\u003c\/li\u003e\n\u003cli\u003eFunctionality: Designed to support expansion modules for complete safety control coverage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 440R-W23219 offers a flexible foundation for building scalable, certified safety relay systems in complex automation environments.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":50192342778154,"sku":"440R-W23219","price":5422.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/shopping_44_68eb87ae-cead-40cc-9134-3ba1f4a5344e.webp?v=1747142082","url":"https:\/\/iqelectro.com\/products\/allen-bradley-440r-w23219-msr310p-modular-safety-relay-base-unit-24v-dc","provider":"IQElectro","version":"1.0","type":"link"}
