For thermoresistances PT100, NI100
• For a three-wires PT100 use cables
with the same diameter
• For a two-wires PT100 short-circuit
terminals 10 and 12.

For signals 0…10V
Comply with polarity
Ri>=110KΩ
1112 9
For signals 0/4…20mA with three-wires
sensors
Comply with polarity
A= sensor supply
Check power supply requirements on
technical data sheet of sensor!
Capacity 12…24V / 30mA for models AD
Capacity 8V / 20mA for models A-B-C
B= sensor ground
