The power meter has 2 solid-state relay outputs (DO1 and DO2). The relay outputs
have 4 operation modes:
• Alarm: the output is controlled by the power meter in response to an alarm condition.
The output turns On (relay closed) when at least one alarm is active. The output
turns Off (relay open) when the alarm is deactivated.
• Energy Output: you can use DO1 only for active energy pulse output and DO2 only
for reactive energy pulse output. You can configure the pulse frequency (pulse/kWh
or pulse/kVARh) and the pulse width.
• Disable: the digital output function is disabled.
• External: the output is controlled by the power meter in response to a command
21000.
