4.4. CONNECTING THE OUTPUTS
4.4.1 Relay output connection
All the outputs are operable at either 12 or 24 volt in al-
ternating or continuous current (do not supply voltage
higher than 30 volt).
To be operative at 24 Vac, an external transform-
er with a double-insulated 24 Vac output must be
installed pursuant to UNE EN61010 standards. There
is an accessory for a 230/24 Vac 50 VA transformer to
connect to the unit.
The power supply intake for the outputs is marked R+
and R- .
The solenoids on the solenoid valves, relays and
contactors are connected between the CR output
common and the corresponding output between R1
and R27 .
The outputs are isolated from the internal circuitry by
relays and protected by a varistor in each one.
The power supplied to the outputs and sensors is
protected by an auto-resettable thermal fuse. The
‘Consultation - Agrónic’ section indicates whether
there is voltage for the outputs or not. When there is
a short circuit in one of the outputs, the fuse will auto-
matically be tripped, limiting the output until the short
circuit has terminated.
