Inputs
The„input„circuits„have„the„characteristics„of„a„high„speed„photocoupler„with„an„isolation„
voltage„of„3„kV.„They„are„protected„against„high„current„and„polarity„inversions.
–„Operating„voltage„5„to„35„V
–„Regulated„input„current„within„the„operating„voltage„range
–„Current„consumed„5/6„mA„(encoder„12/13„mA)
–„Maximum„operating„frequency:„ 6.25„kHz,„200„kHz„for„the„encoder„input.

Warning and fault outputs
A„beacon„column„may„be„connected„to„the„printer„via„the„M12„connector„(yellow)„on„the„
left„hand„side,„or„via„one„of„the„following„outputs„on„the„industrial„interface„board:
„
„
Relays
The„relay„outputs„are„potential-free„dry„contacts.„The„contact„switches„warning„systems„
or„electrical„configurations„connected„directly„to„the„mains„supply.
The„electrical„contacts„are„protected„by„R.C.„cells„(0.1„μF/+„47„Ω).
–„Maximum„voltage:„24„V
–„Maximum„current:„1„A„(AC„or„DC)
„
„
Optocouplers
The„industrial„interface„board„also„provides„optocoupled„outputs„for„an„alternative„
connection„method.
