Warning:
Warning:Warning:
Warning: for the power supply of any active probes, the 24 Vdc available at the +Vdc terminal (J2) can be used. The maximum current is 80 mA, protected against
short-circuits. To supply the 0/5V ratiometric probes, use the 5V available at the +5Vref (terminal J2). The maximum current is 60 mA.
