Phoenix Contact Safety Relay, Dual Channel, 24V DC Supply Voltage - PSR-MS45-1NO-1DO-24DC-SC - 2904955


Choose this safety relay from Phoenix Contact to trigger a response in your equipment in the event of an emergency. Thanks to its dual-channel design, you can use it to monitor two devices at the same time, saving space in busy setups. A wide operating temperature range between -40°C and +60°C means it can withstand harsh settings. The relay also comes with reverse polarity protection to prevent damage from electric hazards.
Installation is simple – just clip the unit onto a DIN rail in either a vertical or horizontal position. A mechanical service life of 10,000,000 cycles makes it suitable for long-term operation, while tough PBT housing has the high thermal resistance needed for use in demanding operations. Relays like this one are commonly used to control and monitor light curtains and magnetic switches.
