Looking for a way to enhance your equipment's safety system and improve reliability? Use this safety relay contact from Phoenix Contact. It measures the performance of the contacts and quickly cuts off power if a fault is detected, preventing damage to both users and a connected device.
With its eight enabling current paths, you can use this relay for multiple operations at once, making it a versatile choice. The wide 5 to 250V AC/DC output switching voltage means you can use it with a wide range of equipment, while a 4kV surge protection rating prevents damage from electrical malfunctions. You'll find it easy to identify the device's status thanks to the LED (light-emitting diode) signal.
This component is easy to mount on DIN rails without the need for specialist tools. It can be installed in any position to suit your individual setup. The PBT (polybutylene terephthalate) casing has high impact resistance so the relay is protected against the demands of challenging environments.

• Silver tin oxide contact material has low contact resistance for reliable connections
• IP20 (ingress protection) rating indicates protection against damage from manual handling
• Broad operating temperature range of -20°C to +55°C for use in harsh environments
