RS485 Modbus RTU communication
Contacts capacity 2 A/250 Vac for resistive loads.
NB: see picture below
For strain-gauge sensors (4 wires+ 2
calibration wires) or Melt sensors
• Comply with polarity.
•
To perform semi-automatic calibration,
connect the 2 calibration wires to the relay
contact Q2 and set properly the parameter
for output Q2.
•
When shielded cable is used, it should be
connected to the pin 13 (EXC-).
For linear potentiometers
• Use potentiometers with resistive value
greater than 200 Ω.
• When shielded cable is used, it should be
connected to pin 13 (EXC-)
