Buy an ATO 4-digit display controller for DC current sensor. It is equipped with an RS-485 communication interface and Modbus-RTU protocol, providing analog outputs, relay alarm outputs, and digital input/output. Parameters such as ratio, alarm, and communication can be set and controlled via the keypad on the instrument panel to meet specific needs.
Power frequency withstand voltage:
AC2kV 1min between power supply//switching output//current input//voltage input and transmitter//communication//switching input;AC2kV 1min between power supply, switching output, current input, and voltage input; AC1kV 1min between transmitter, communication, and switching input; Insulation resistance: input and output terminals to housing >100MΩ.
Tips: Why do DC current sensors need a digital panel meter?
A DC current sensor only converts the current into an electrical signal, such as a small voltage or current, but this signal by itself is not easy to read or understand. A digital panel meter is needed to take that sensor signal, scale it to the correct range, and display it as a clear numerical value in real time. This makes the measurement visible to operators, allows easy monitoring, and in some cases also provides alarm or control outputs for added functionality.
