Remote keyboard connection

The following rules must be followed when 
doing the connections:
-  do not apply loads greater than the ones 
included in these specifications on the out-
puts;
-  when connecting the loads, carefully 
observe the connection diagrams; 
- keep the power cables separated from the 
signal cables to prevent interferences.

Analogue inputs 
The analogue inputs are 5: 
• 3 inputs for the NTC temperature 
probes; 
• 1 configurable input for NTC probe or 
for signal 4...20 mA. The following inputs 
are identified as AI1…AI5.

Digital inputs
The digital inputs, free from voltage, are 6 
and are identified below as ID1…ID6. 

Remote keyboard connection
Connect the three wires as per the wiring 
diagram.
Important! Do not connect the keyboard 
with the instrument powered on. Avoid 
the short-circuit between cables with the 
instrument powered on: they could dam-
age the instrument.

User interface

User interface
The interface, consisting of the remote 
keyboard, makes it possible to carry out 
all operations related to the use of the 
instrument, in particular: 
• setting the operation mode 
• manage the alarm situations 
• check the status of resources 

Displays 
The device can communicate any type 
of information regarding its status, con-

no. 3 shielded electrical cables 
not shielded (max. length 100 m;  
minimum section 0.5 mm
