Connecting current-output pressure probes
For information on the maximum number of probes that can be connected
see the table at the beginning of this paragraph. For details on the operating
range see the data sheets supplied with the probes. The controller can
be connected to all CAREL SPK* series active pressure probes or any
commercially available pressure probes with 0 to 20 mA or 4 to 20 mA signals.

Connecting 0 to 5 V ratiometric pressure probes
For information on the maximum number of probes that can be
connected see the table at the beginning of this paragraph. For details
on the operating range see the probe data sheets. The controller can
be connected to all CAREL SPKT series active pressure probes or any
commercially available pressure probes with 0 to 5 V ratiometric signals.
Important:
• ratiometric probes are powered by the controller via terminal +5 VREF;
• ratiometric probes cannot be powered by an external source.

Max. number of connectable digital inputs
The controller allows the universal inputs/outputs to be congured as
non-optically isolated, voltage-free digital inputs. In any case, the inputs
must be connected to a voltage-free contact.

Tab. 5.c
Important: the maximum current allowed on the digital input is 10
mA. Therefore the rating of the external contact must be at least 10 mA.
Connecting ON/OFF inputs
There is no particular restriction on the maximum number of inputs that
can be connected. For details on the operating range see the Technical
Specications table (see chap. 12).

Connecting fast digital inputs
Important: the wires connecting the fast digital inputs/counters
must be shielded to avoid causing electromagnetic interference with the
