Omron G9SX-GS Safety Relay, 24V dc, Dual-Channel

The G9SX-GS safety relay is designed to support maintenance mode and normal operation mode in a safe way.

Two operation modes to support auto switching for applications where machine and worker co-operate and manual switching for applications with limitations in operation such as machine maintenance
Clear LED diagnosis of all inputs and outputs
Applicable up to Category 4 acc. EN 954-1
