3.4 I/O Interface fundamentals
There are 7 types of CN1 interface signal as following:
 Switching volume input,
,
A lateral pole is connected to COM+ via 3kΩ
resistance in series for one internal photoelectric coupling; K lateral pole is connected
to input terminal for one photoelectric coupling.
 Switching volume output,
,
E lateral pole is connected to DG terminal, C pole
to output terminal for two internal photoelectric couplings. The max. current ≤15mA
 Switching volume output,
,
E lateral pole is connected to DG terminal, C
pole to output terminal for two internal Darlington output photoelectric couplings. The
max. current ≤50mA
 Pulse input interface,
,
A lateral pole is connected to positive input
terminal via a resistance in series and K pole to negative input terminal for one
internal high speed photoelectric coupling.
 Differential output,
,
internally connecting the output terminal of
differential output chip 26LS31
 Analog signal input,
,
interior is the difference-analog amplified circuit input.
 Analog signal output,
,
internally connecting the output of operational
amplified circuit.
