Installing Wiring for I/O Devices

Wiring to Inductive Loads
When wiring outputs to inductive loads, use of external suppression circuits is
recommended. If possible, the external suppression circuits should be
connected across the actual load. If that is not possible, external suppression
circuits should be connected to each point that will drive an inductive load.
AC Inductive Loads
For AC inductive loads, the snubber network
should consist of a 250 V AC, 0.1µF capacitor
connected in series with a 100 Ohm ½ Watt or
higher resistor. A capacitor with a different
working voltage may be chosen, as appropriate
for the application.
Recommended snubber packages include
104M06QC100 or 104M06RL100 from Paktron.

DC Inductive Loads
For DC inductive loads, a diode should be placed
across the load as shown below. Recommended
diodes include:
1N4934 100 V, 1A;
1N4936 400 V, 1A;
1N4937 600 V, 1A.
These diodes are available from most
manufacturers.
