The ePRO Plus 2-Channel Alarm Expander Kit adds two additional alarm relays to your ePRO Plus device. This kit can be used in case the application requires each alarm type to be assigned to a different relay contact.

Besides the internal alarm relay that is available in the ePRO Plus Meter, adding an alarm output expander offers even more flexibility in assigning different alarms to different physical relay contacts. For each alarm setting inside the ePRO Plus Meter, you can either select to trigger the internal alarm relay when an alarm is active, or select one of the externally available relays.

The ePRO Plus 2-Channel Alarm Output Expander is equipped with latching relays for the lowest power consumption (< 1mA steady state). Each contact can switch up to 8A at 250Vac or 30Vdc. You can connect more than one Output Expander on the QuickLink bus using the address selection DIP switches.
