To protect people and equipment from electrical hazards, wire up this safety relay from Siemens. The device responds to an error detected by a connected sensor by sending a signal to the next layer in your system. It's a versatile unit you can use in conjunction with floating, non-floating, single-channel and dual-channel sensors, among other components. You'll find products like this used in workplaces with automated machinery, including the food processing industry, oil and gas production and automotive manufacturing.

• Functions reliably in temperatures ranging between -25°C and +60°C
• Mountable in any position for fitting flexibility
• Protected against voltage surges of up to 800V for electrical safety
• IP20-rated as touch-proof against fingers and tools larger than 12mm
• Small size of 17.5 (W) x 100 (H) x 121.6mm (D), so it's a space-saving component

The device sends a response in just 60ms in both automatic and monitored start applications, saving precious time if there's an incident.

This relay has a 24V DC supply voltage rating, so it's compatible with common energy sources.
