Wiring of digital outputs
The digital output (terminals 31/32, 51/52, 41/42, 81/82) can be wired as Open
Collector or as NAMUR contact for connection to a NAMUR amplifier.
The outputs are wired to "NAMUR" on delivery, unless "Open Collector" was specified in the
purchase order.

NOTICE:
● An operating current range of 20 mA is recommended.
● I
max
at the open collector connection must not exceed 100mA., otherwise
the output may be destroyed.
● The maximum possible frequency of the impulse output depends on R
L
and
the cable length (cable capacitance).
● A higher frequency requires a lower R
L
. For this case a low capacitance cable
is recommended.
