Modbus Instructions

LP-ID MODBUS® RTU Current Transducer

The LP-ID transducer converts an ac current input into an output signal which is proportional to the rectified arithmetic mean of the input.
Accurate measurement assumes a sinusoidal input waveform.
The output of the transducer is via RS485 serial data bus using MODBUS® RTU protocol.

Ordering information: LP-ID, input, power supply.
Example: LP-ID, input 0-1A, supply 110Vdc.
