5.4 Parallel outputs
The unit provides 25 push-pull outputs which are short-circuit proof. The
separate common output voltage for the outputs must be applied to screw
terminal 1 (COM+).
The maximum voltage to COM+ should not 27 volts, otherwise no
continuous short-circuit proof of the outputs can be guaranteed.
The voltage drop between COM+ and an output in HIGH state is approx. 1 volt
(unloaded).
5.5 DATA STABLE output
The output for bit 25 can be configured as a DATA STABLE signal by means of
the DIL switch 6 PIN 25 FUNCTION A (see section “6 - DIL switch settings” on
page 39). In this case a LOW state indicates that parallel output data is stable
and will not change.
The rising edge of the signal still guarantees stable data and can be used for
remote Latch of the parallel data. The LOW duration of the signal is at least 1/3
of the
setting.
