SKU: MAX-MB-3I-1-15A Category: I/O extension modules

Functioning
The module is designed to work with current transformer with 5 A secondary current.
The module continuously measures the current flowing through the measurement inputs. Readout of recorded current strength and setting of all communication parameters are 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.

Reset communication settings
Under cover is available code switch.
Details of resetting available in the instructions below.
