Warning: for the power supply to any active probes, the +21 V available on the VDC terminal can be used, maximum current
available Imax= 60 mA, protected against short-circuits. For the power supply to the 0 to 5 Vdc ratiometric probes, use the +5
VREF, maximum current available Imax= 60 mA, protected against short-circuits.
Specications
Time constant 0.5 s
Precision ± 0.3 % of full scale
Classification of measuring circuits Category 1 (IEC EN 61010-1)
Tab. 2.f
Warning: separate as much as possible the probe and digital input signal cables from the cables carrying inductive loads and
power cables to avoid possible electromagnetic disturbance.
