Schneider Electric XPSU Emergency Stop Safety Relay, 24V ac/dc, Single Channel, 2 Safety Contacts

The XPSUAB range of safety relay modules are predominantly designed to monitor two-hand control stations, used in applications such as:
• Monitoring emergency stops
• Antivalent contacts
• Guard switches
• Magnetic switches
• Proximity safety switches
• PNP sensors
• RFID safety switches
• Safety light curtains

Safety relays with a clever design that allows the monitoring of dangerous operations, to initiate a dangerous movement both operators must be activated within an interval of 0.5 seconds which is referred to as synchronous activation. If one of the two pushbuttons is released during a dangerous operation, the control sequence is automatically cancelled. Users can resume the dangerous operation through both pushbuttons returning to their initial position and reactivating them within the required time interval.

• Automatic, manual and monitored starts
• Type 4 light curtains conforming to IEC 61496-1 which have solid-state safety outputs with test function
• These functions are selected, and the start function can be configured by selector switches on the front face.
• A solid-state diagnostic output with complete status information facilitates maintenance.
• 6 LEDs on the front face provide information on the monitoring circuit status
• 1 safety input
• 2 On/Off control outputs which are configurable pulsed
• 1 single safety changeover output
• Removable terminal blocks for the connection type

• Safety levels for the relay include: Can reach PL c/category 1 conforming to ISO 13849-1, Can reach SILCL 1 conforming to IEC 62061 and Can reach SIL 1 conforming to IEC 61508
• NC pair, PNP pair, Antivalent pair and OSSD pair electrical circuit type
• Forms part of the preventa safety automation range of products
• This relay has a rated supply voltage of 24 V AC - 15...10 % and 24 V DC - 20...20 %
• The device has an internal and electronic input protection type
