Data: Inputs
Probe Input
● The inputs I_1 (X37.4) and I_2 (X38.4) can be used as probe inputs.
● Internally, the outputs
24V (> 18 V) / 100 mA. The current can be distributed to the four outputs.
If more current is required in total, you have to supply, in addition, 24V
externally.
● Each of the short-circuit proof outputs can be loaded with 0.5 A. In total,
a maximum of 1 A is possible.
● An o-ring at the root of the thread between the female connector insert
and the electronics housing assures the tightness of the M12 female con‐
nectors. Without this o‑ring, neither the protective cap nor the connector
are tight!

Probe inputs are "rapid" inputs. For control use bounce-free switch‐
ing elements (e.g. electronic switches) to avoid incorrect evaluation.
