Relay Outputs (continued)
The OUT 1 NO contact and the OUT 2 contact are
protected by varistor against inductive loads with
inductive components up to 0.5 A.
OUT 1 contact rating is 3A/250Vac resistive load.
OUT 2 contact rating is 1A/250Vac resistive load.
The number of operations is 1 x 105at specified rating.
Notes:
1.To avoid electric shock, connect power line at the
end of the wiring procedure.
2.For power connections use No 16 AWG or larger
wires rated for at last 75 °C.
3.Use copper conductors only.
4.Do not run input wires together with power cables.
Inductive Loads
Employing the following recommendations will help
avoid serious problems that may occur when relay outputs
are used with inductive loads.
High voltage transients may occur when switching
inductive loads. Through the internal contacts these
transients may introduce disturbances that can affect the
performance of the controller.
For all the outputs, the internal protection (varistor)
assures a correct protection up to 0.5 A of inductive
component.
The same problem may occur when a switch is used in
series with the internal contacts as shown in Figure 8.
