The PSSR/2 control unit is designed to be used in conjunction with Tapeswitch™ pressure sensitive sensor products to make a complete safety system. Sensors may take the form of safety mats, sensing edges, bumpers, or ribbon switches but must incorporate an integral end of the line resister.
When the PSSR/2 is used with suitable Tapeswitch™ sensing edges, bumpers, switches or mats the system meets the requirements of EN13849-1:2006 PLd, EN62061 SIL2 and is a Category 3 configuration. It is an extremely compact unit which has a 22.5 mm DIN rail enclosure ideal for mounting in control panels. The PSSR/2 has a manual or auto reset function and operates from 24 VDC.

• Works with all mats, edges, bumpers, and switches
• Category 3 PLd SIL2
• End of line resistor monitoring
• DIN rail mounted
• 24 VDC supply voltage
• Manual or auto reset
• Self-monitoring
