• Schneider Electric Preventa Series Safety Relays - XPS Universal Range The XPS SUAT series safety relay modules are used to protect both the user and the machine by immediately stopping dangerous operations when instructed by the user or when a problem is detected in the safety circuitry. This Type of safety relay is used primarily for monitoring purposes such as: Switch enabled by monitoring protection device of emergency stop circuit Mechanical guard switch Magnetic switch with valence or 2NC contact Proximity safety switch with antivalent contact PNP sensor 1 PNP + NPN Sensor RFID safety switch Type 4 light curtain 4-wire sensing mat or edge The XPSUAT safety module has an instantaneous open-circuit safety output of stop category 0 and a time-delay output of stop category 1 to control motor deceleration and complete stop (e.g. motor braking with variable speed drive). When the set delay time elapses, the power is turned off by opening the time delay output circuit. You can also select the delay time from 0.1 seconds to 15 minutes with the selector switch on the front Features and benefits Selector switch allows you to set the function Front Solid state diagnostic output with complete status information makes it easy Maintenance To monitor more valence contacts with this safety module, non-valence contacts can be connected in series with NC and NO can be connected in parallel 8 LEDs on the front Display information Monitoring circuit status Removable Terminal Block with 27 terminal connection Type with secure extended connections Automatic, manual and monitored activation 2 positive safety inputs and 1 negative safety input at 24 VDC 4 configurable on/off pulse outputs The safety levels for the Schneider Electric Preventa safety module - XPSUAT33A3AC relay include: PL e/Category 4 for normally open relay contacts conforming to ISO13849-1, capable of reaching SILCL 3 for normally open relay contacts conforming to IEC62061, capable of reaching SIL 3 for normally open relay contacts conforming to IEC61508, capable of meeting PL c/Category 1 for normally closed relay contacts conforming to ISO13849-1, capable of reaching SILCL 1 for normally closed relay contacts conforming to IEC62061, capable of reaching SIL 1 for normally closed relay contacts conforming to IEC61508 It forms part of the Preventa safety automation series of NC pair, PNP pair, valence pair and OSSD pair electrical circuit types Product The rated supply voltage for this relay is 48 ~ 240 V ac/dc -10 → 10% This device has internal and electronic input protection Type Associated fuse rating: 10 A gG without relay output circuit Conventional free air Thermal current: 16 A Maximum line resistance: 60 °
