Digital inputs

The meter is equipped with four digital input ports (S1 to S4). You can configure the digital inputs for use in status monitoring or input metering applications.

The meter’s digital inputs require an external voltage source to detect the digital input’s on/off state. The meter detects an on state if the external voltage appearing at the digital input is within its operating range.

The digital inputs require a 18 - 30 V AC or 12 - 30 V DC external voltage source to detect the digital input’s on/off state.
