Allen-Bradley 440R-C23136 Safety Relay Module

Allen-Bradley 440R-C23136 is a Minotaur MSR131RTP monitoring safety relay module in the Guardmaster 440R family. This single-function safety relay is powered by 230V AC and offers dual-channel safety control, with three safety contacts and two auxiliary contacts for status signaling. Catalog number 440R-C23136 identifies the MSR131RTP-based device, designed to supervise safety-related circuits and to generate appropriate safety outputs when monitored conditions are met or not met. As part of Rockwell Automation's Minotaur line, it provides a compact, field-installable solution for integrating with safety sensors such as interlocks and safety switches, enabling reliable fault signaling to downstream safety controllers and PLCs. The MSR131RTP variant is intended for industrial environments where safe, monitored control of hazardous machinery is critical, delivering predictable performance in safety-rated control architectures and enabling straightforward validation of circuit integrity during commissioning and maintenance.
