* O.C. : Denotes Open Collector
Note 1: Open Collector outputs require external pull-up resistors. When connecting
“User +24VDC” to pull-up resistors, their resistance value must not be lower than
2kOhm.
Note 2: When using “User +24VDC” as control supply voltage for pins 2-6, 9, 10, 24
and 26, then GND and GND_ISO must be shorted externally (for example pins 17
and 36).
