Relay, Single Function, Safety, with Delayed Outputs, 115VAC

The GuardMaster MSR138DP relay is a single-function safety relay designed for use with light curtains and other safety inputs, operating at 24 volts AC/DC. Distributed by BSP Automation, this relay features delayed safety outputs with adjustable time delays ranging from 0.5 to 10 seconds and offers flexible reset options including automatic, manual, or monitored manual modes. It includes one or two normally closed inputs, two normally open safety outputs, and three normally open delayed safety outputs with removable terminals for straightforward installation. Built to meet functional safety standards like ISO 13849-1 and IEC 62061, the GuardMaster relay helps simplify system design while ensuring reliable protection. Additionally, when paired with intelligent GSR safety relays and the optional EtherNet/IP interface, it can provide valuable diagnostic information to reduce downtime and enhance operational efficiency within connected industrial environments.
