Configuring Relay Outputs
The PowerSmart Socket PQM has one embedded relay output
(RO1) and can provide one additional expansion module with
a total of 6 relay outputs (RO2 through RO7). I/O numbers
are automatically assigned to outputs.
To configure the relay outputs in your meter, select General
Setup from the Meter Setup menu, and then click on the
Relay Outputs tab. Relays that are not present in your meter
are not shown.
The available relay options are described in the table below.
