In addition to local display, this DC digital panel meter can also be connected with control equipment and computer for industrial monitoring and controlling applications. Besides, it has options of external ports to meet users’ specific needs, supporting RS485 communication interface, Modbus RTU protocol, alarm-triggered relay output, and digital input/output. According to individual application needs, the transformation ratio, communication, etc. can be set and controlled through the function keys on the front panel.
