Increasing contact life span
To increase the life span of your contacts and protect the unit from potential damage by reverse-
EMF, connect:
A clamping diode in parallel with each inductive DC load
An RC snubber circuit in parallel with each inductive AC load
Analog inputs
Note:
Shields should be connected at the signal source.
Analog Input wiring, current (AN0-AN1)
2 or 3-wire
4-wire
Analog Input wiring, voltage (AN2-AN3)
Note:
If either I16 or I17 is wired as an npn digital input, the remaining input may not be wired as an
analog input.
