Relay output connection

The A100E can control two relay outputs.
The outputs can be associated to digital thresholds that can be programmed as required.
Refer to “Threshold control” paragraph for the functional aspects.
Refer to “CONFIGURATION” section of the manual for the programming modalities.

As output, a normally open (NO) contact that is voltage free is available to the user for each relay.

The contact rating is 0.5A at 24 Vdc.
If contact drives relay coils or inductive loads, a shut-off circuit must be provided in
parallel to the contact.
