Interposing Relays
This sample illustrates the use of interposing relays in a system of this type. Interposing relays are used
microLoad.net’s DC Digital Inputs. Interposing relays are also used with the microLoad.net’s digital outputs to
provide greater load capacity needed to energize the coils of the pump motor starters.
