OSSDs (Output Signal Switching Devices)

SFM-…2:

Two OSSDs with 4 normally closed contacts

Auxiliary contactsOne auxiliary contact per channel. InputsOne start input per channel and one feedback loop per channel. Freely usable on SFM-B... Logic functionsProgrammable with AsiMon software. All safety components can be programmed with different functions as inputs. The inputs can be linked with AND or OR gates. With the monitors SFM-B…, additional logic functions such as FlipFlop, switch-on delay, turn-off delay or pulses are available. The number of links and the memory depth are larger than on the SFM-A… devices.
