Schmersal SRB 301LC Safety Relay

Schmersal SRB301LC is a two-channel safety relay with a 24 VAC/DC input, part of the Schmersal Protect SRB family for safeguarding machine operation. This module accepts 24V power and provides three safety contacts for safe switching of outputs, enabling interlocks, emergency-stop circuits, and safety-door or gate monitoring in automation systems. The unit is designed for compact installation and is IP20-rated, making it suitable for panel mounting in harsh production environments. As a dual-channel safety relay, SRB301LC ensures that both safety channels are satisfied before allowing a restart, supporting safe, monitored shutdowns and controlled energy release in line with standard safety practices. The SRB301LC-24V variant targets 24V power architectures, while related variants such as SRB301LC/B and SRB301LC/8 offer alternative wiring schemes and channel configurations to fit different safeguarding applications. This relay is typically used in conjunction with safety switches, emergency-stop devices, and guard interlocks to provide a reliable, code-compliant safety control point within an automation system.
