Technical Specifications Condition New/Never Used Surplus Brand Allen-Bradley Category Safety Systems Part Number 440R-W23219 Subcategory Safety Relay Series MSR310P Voltage 24 VDC Output Configuration 0 Safety Outputs, 3 N.O. Auxiliary Solid-State Outputs Reset Function Automatic / Manual Monitored Communication Interface RS-232 Enclosure Width 35 mm DIN Rail Mount Terminal Type Removable Terminals Weight 0.5500 lb Information About 440R-W23219 The 440R-W23219 is part of the Guardmaster modular safety relay family and serves as the base unit for MSR300 series modular relay systems. 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. Key Features: Application: Modular safety relay base for configurable safety systems. Voltage: Operates at 24 VDC for standard low-voltage industrial environments. Output Configuration: 0 safety outputs, 3 N.O. auxiliary solid-state outputs. Reset Type: Supports both automatic and manual monitored reset modes. Enclosure Size: Compact 35 mm housing for efficient DIN rail mounting. Connectivity: Includes RS-232 interface for optional diagnostics/configuration. Compliance: Certified to CCC, CE, CUL, and UL standards for global application. Functionality: Designed to support expansion modules for complete safety control coverage. The 440R-W23219 offers a flexible foundation for building scalable, certified safety relay systems in complex automation environments.
