Caution for AC Loads
1) Relay output case
This PLC does not have any internal protection
circuitry on the relay outputs. For switching AC on
inductive loads, a surge absorber (0.1
µ
F + “100
to 120
Ω
”) should be installed in parallel with the
load. The relay contact life decreases significantly
if this is not done.
Besides protecting the internal circuity of the
PLC, a surge absorber decreases the noise
emissions to the load.
Component Side of Loads
The output contact of the PLC should be connected to
components consistently as indicated in the figure
Note: If using another output type, please replace
symbol with appropriate symbol.
