Universal inputs
Universal inputs/outputs are distinguished by the letter U. They can be configured from the application
for many different uses such as NTC, 4-20mA, voltage inputs, dry contact, or PWM. The maximum
number of analog inputs that can be connected to the universal inputs/outputs depends on the type
used.
WARNING: The 21VDC available at the +Vdc terminal (J2) can be used to power any active
probes, the maximum current is 150 mA, thermally protected against short-circuits. To supply
the ratiometric 0 to 5V probes, use the +5VREF (max: 60 mA) present at terminal J24.
