0-20mA differential input; 16-bit resolution, 0.1% accuracy, 10 ohm
input impedance.
Thermocouple inputs
1
J, K or T type thermocouple with on-board cold-junction
compensation.
Cold junction compensation accuracy ±1º over ambient temp
range: -40º to +70ºC.
Power supply
1
9-30 VDC 0.6 Amp CSA certified Class 2 power supply. For use in
Class 1 Div 2 explosive areas, the power supply must be approved
for Class 1 Div 2 use.
