mall...Extralarge: 0 to 10 V analogue outputs
On terminals VG and VG0 the controller provides optically-isolated 0 to 10
V analogue outputs, to be powered externally at the same voltage as the
controller, i.e. 24 Vac or 28 to 36 Vdc. The connection diagram is shown
in the figure below. The 0 V supply voltage is also the voltage reference
of the outputs. See the Technical Specifications table for details on the
output current, output impedance, etc. (see chap. 12).
Note:
•
the analogue output can be connected to the CONVONOFF0 module
to convert the 0 to 10 V output into an ON/OFF relay output;
•
a 0 to 10 Vdc analogue output can be connected in parallel to other
outputs of the same type, or alternatively to an external voltage
source. The higher voltage will be considered. Correct operation is not
guaranteed if actuators with voltage inputs are connected;
•
if optical isolation is not required, the VG-VG0 analogue outputs can be
powered at the same voltage on G-G0: connect G0 to VG0 and G to VG.

5.5 Connecting the Ultracap module
The Ultracap module can be connected to power the controllers in the event
of blackouts:
1.
c.pCOmini controller: the module guarantees temporary power to
the
controller and driver
for enough time to close the electronic
valve (40s with forced closing of the valve, 60s without forced closing
of the valve). NB: with Vdc power supply, forced closing of the
electronic expansion valve is not managed in the event of blackouts.
