Rated maximum voltage in common mode: 60 VDC or VAC.
G.3.1
Resistance (TC6622, TM6612 and TM6630)
The resistance measurement function is obtained by configuring the device as follows:
Sensor: PT100 and Unit: Ohm for the 400 Ohm gauge.
Sensor: PT1000 and Unit: Ohm for the 3600 Ohm gauge.
Gauge
400 Ohm
3600 Ohm
Temperature coefficient < 10 ppm/°C from 0°C to 18°C and from 28°C to 50 °C.
•
Automatic wiring diagram detection: 2 wires, 3 wires or 4 wires.
•
In the 2-wire assembly, the measurement includes the line resistances.
•
In the 3-wire assembly, add the line resistances imbalance.
