Function description 
 

The safe expander module FSEM expands an existing circuit. As the output relays are monitored with the base unit feedback loop it is possible to reach the same safety level to the contact expander module. Base units can be all safety devices with a monitored
feedback loop. Fiessler Elektronik offers the safety light curtains series ULVT, ULCT and BLVT, BLCTas well as the programmable safety controller FPSC. It is possible to realise application up to cat. 4 ref. EN 954-1. The achievable category is depending on the base unit and the electrical connection
