This programmable master unit operates on 20.4–26.4 VDC power input with 5.28W consumption and delivers flexibility through 22-point embedded safety I\/O configuration. The relay supports applications up to PLe, Category 4 per ISO 13849-1 and SIL CL3 per IEC 62061, making it suitable for demanding safety-critical environments. Integration with Studio 5000 Logix Designer or Connected Components Workbench software enables rapid configuration using pre-defined drag-and-drop safety function blocks. The unit accommodates up to two Micro800 Plug-in Modules and features embedded communication via USB programming port and non-isolated serial port for RS-232 protocols. An optional Ethernet plug-in module allows diagnostic data transmission to CompactLogix or Micro800 controllers, supporting connected enterprise architectures. The relay includes two single-wire safety input\/output points for interlocking between multiple Guardmaster safety relays.\n\n\u003ch2\u003eKey Features of Allen Bradley 440C-CR30-22BBB\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e22-point configurable safety I\/O: 12 safe digital inputs, 4 safe digital outputs, 6 PulseTest outputs\u003c\/li\u003e\n\u003cli\u003eSupports up to ten dual-channel safety circuits controlling five output zones\u003c\/li\u003e\n\u003cli\u003eSafety-rated to PLe Category 4 (ISO 13849-1) and SIL 3 (IEC 62061)\u003c\/li\u003e\n\u003cli\u003eUSB and RS-232 communication ports with optional EtherNet\/IP module\u003c\/li\u003e\n\u003cli\u003eModbus RTU serial protocol support for integration with third-party devices\u003c\/li\u003e\n\u003cli\u003eIP20 rated housing: 90mm H × 100mm W × 80mm D, weighing 0.423 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specs of 440C-CR30-22BBB\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Input:\u003c\/strong\u003e 20.4–26.4 VDC, 5.28W consumption\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -5°C to 55°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety I\/O:\u003c\/strong\u003e 6 configurable, 12 inputs, 4 outputs, 6 PulseTest outputs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunication:\u003c\/strong\u003e USB, RS-232, Modbus RTU, optional EtherNet\/IP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental:\u003c\/strong\u003e 90% RH max, 10g shock acceleration, 0.35mm vibration displacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e C-UL-US Listed, CE, EN 61000-6-2\/6-4, EN 60947-1\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications \/ Use Case\u003c\/h2\u003e\n\nThe 440C-CR30-22BBB excels in machine safety applications requiring flexible safety circuit management across multiple zones. Manufacturing facilities deploy this relay for emergency stop systems, interlock monitoring of guards and gates, light curtain integration, and two-hand control circuits. The configurable architecture allows one relay to manage diverse safety functions within a single machine or cell, reducing panel space and wiring complexity. Process industries utilize the relay for isolation lockout sequences and safe motion control in conveyor systems. The EtherNet\/IP option enables condition monitoring and predictive maintenance strategies by transmitting diagnostic data to plant-level control systems. Integration with Logix platforms streamlines programming for OEMs building standardized machine designs. The relay's ability to handle multiple safety inputs simultaneously makes it ideal for complex machinery requiring coordination between mechanical guards, area scanners, and operator interfaces while maintaining full compliance with international functional safety standards.\n\n\u003ch2\u003eRelated Resources\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/\" target=\"_blank\"\u003eLeadTime.ca – Industrial Automation Components \u0026amp; Repair Services\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/collections\/allen-bradley\" target=\"_blank\"\u003eView All Allen Bradley Products\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/blogs\/learning-center\/top-plc-brands-compared-siemens-allen-bradley-mitsubishi\" target=\"_blank\"\u003eTop PLC Brands Compared: Siemens, Allen Bradley \u0026amp; Mitsubishi\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-5069-l320er\" target=\"_blank\"\u003eAllen Bradley 5069-L320ER CompactLogix Controller\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/leadtime.ca\/products\/allen-bradley-1756-en2tr\" target=\"_blank\"\u003eAllen Bradley 1756-EN2TR EtherNet\/IP Module\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":47870786568491,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4671\/7995\/files\/Leadtime_3ece33db-72f1-4590-8f58-26936314c889.png?v=1723532089","url":"https:\/\/leadtime.ca\/products\/allen-bradley-440ccr3022bbb","provider":"LEADTIME","version":"1.0","type":"link"}
