Schneider Electric | Preventa XPSAK Series | Safety Relays Simple and effective safety monitoring has never been more crucial in today's highly automated world. Prevention is key to site safety, that's why Schneider Electric offers a Safety Relay in the form of the 'Preventa XPSAK' module that is second to none. Being able to monitor faults with devices along a circuit has the power to stop emergency situations from even occurring. Features and benefits:

• Provides 3 N/O safety relay outputs plus 1 N/C volt free signalling output


• Monitoring of the start button or automatic starting can be chosen.


• 24 V DC option incorporated for each supply voltage version


• Monitoring of single safety functions, providing an automated solution for use with applications such as emergency push stop buttons or switches.


• Slin in design, with just 45mm of width meaning it can fit nicely even in space constraint spaces.


• 35 mm symmetrical DIN rail support, offering flexible and versatile safety system installation.


• Local signalling in the form of LEDs.

Protection ratings & Safety features (see datasheet for specifics) -

• Impressive line resistance is available, varying between 90 to 100 Ohm (Ω).


• Input protection type is internal, electronic.


• EN1088/ISO 14119, EN 60204-1, EN/IEC 60947-5-1, EN/ISO 13850


• CSA, TUV & UL listed


• IP 40 (enclosure) for protection against small objects up to 1mm such as tools, wires and small wires.


• IP 20 (terminals) for protection against solid objects such as fingers, smaller tools up to 12mm.

Applications - All dangerous machinery requires an automated solution to prevent harm to immediate users and also prevent damage to the machinery. Below are some of the safety applications.

• Monitoring type 4 Safety light curtains with semi-conductor outputs according to EN61496-1.


• Time delay input if needed allowing you to set up your own time function.


• Two-hand control safety circuits


• Sensing mats and edges
