Protect your industrial system from hazards using this safety relay from Phoenix Contact. It features three force-guided safety contacts that monitor changes in the electrical circuits and cut off power if one of them detects a malfunction. You can use with emergency stops, light grids and safety door monitoring, making it a versatile choice. An integrated fuse PTC resistor and suppressor diode protect the relay from electrical short circuits and surges.
For added versatility, this relay is compatible with both single-channel and two-channel devices. An LED display shows its operating status for quick configuration and as it works automatically, you don't need to spend time on manual configuration. A mechanical service life of 10,000,000 cycles means you can rely on this component for long-term use. Combined IP20 (ingress protection) and IP54 ratings indicate it's protected against objects over 12mm, limited dust entry and water splashes.
