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 |
