Product Information / Produktinformation A6312
Rotational Speed Monitor
Function outputs
Opto − decoupled collector / emitter lines
Out 1−1 C / Out 1−1 E
Out 1−2 C / Out 1−2 E
Out 2−1 C / Out 2−1 E
Out 2−2 C / Out 2−2 E
Maximum values for alarm outputs
active state of function outputs
Open circuit / closed circuit mode
Selectable by means of external signal inversion at binary inputs d24 and z24, only for the
function outputs Out 1−1 and Out 2−1.
Outputs Out 1−2 and Out 2−2 are invariably fixed to open circuit mode

C−E off: max. voltage U
C−E conducting: max. current I
conducting in the open circuit mode
switched of in the closed circuit mode
d24 = HIGH / open → open circuit mode
d24 = LOW → closed circuit mode
z24 = HIGH / open → open circuit mode
z24 = LOW → closed circuit mode
LOW: 0 ... +3 V
HIGH: 13 ... 48 V
