• Schneider Electric Preventa Series Safety Relays - XPS Universal Range XPS SUDN 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 RFID safety switch Type 4 light curtain Features and benefits Selector switch can be used to configure functions Front Solid state diagnostic output with complete status information facilitates Maintenance To monitor more valence contacts with this safety module, non-valence contacts can be connected in series with NC and NO in parallel 16 LEDs on the front Display information Monitoring circuit status 32 terminal connection Type removable Terminal Block with secure extended connections Automatic, manual and monitored activation 6 safety inputs and 7 on/off configurable pulse outputs 1 solid state diagnostic output with full status information 3 NO + 1 NC Safety Output The safety levels for the Schneider Electric Preventa safety module - XPSUDN33AP 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 This relay is rated for supply voltage 48 ~ 240 V ac/dc -10 → 10% This device has internal and electronic input protection Input Associated fuse rating: 10 A gG for NO relay output circuit, 4 A gG for NC relay output circuit Conventional free air Thermal current: 16 A Maximum line resistance: 60 °
