Measurement functions |
Number of channels: 2, for temperature measurement with thermocouple (voltage measurement not available) |
Input connectors |
Thermocouple input: plug-in connector, Recommended wire diameter: single-wire, 0.14 to 1.5mm2, braided wire 0.14 to 1.0 mm2 (conductor wire diameter min. 0.18mm), AWG 26 to 16
Input impedance: min. 5 MΩ (with line fault detection ON/OFF), Max. rated voltage to earth: 300V AC, DC (with
input isolated from the unit, the maximum voltage that can be applied
between input channel and chassis and between input channels without
damage) |
Temperature measurement range Note: Upper and lower limit values depend on the thermocouple
