The module is designed to work with current transformer with 5 A secondary current.
The module continuously measures the current flowing through the measurement input. Readout of recorded current strength, setting of all communication parameters are all carried out through RS-485 port using the MODBUS RTU communication protocol. Power up is indicated by a green LED U light. Valid data exchange between the module and the second device is indicated by a yellow LED Tx light.
The transducer measures the effective value of TrueRMS current, which ensures high accuracy even with distorted flow.
