QE-CURRENT-485 CURRENT CONVERTER / CURRENT ANALYZER

The QE-Current-485 by Qeed is a Modbus current and voltage analyzer capable of converting most outputs from current or AC current and voltage sensors—such as current transformers, voltage transformers, Rogowski coils, and Hall effect sensors—into a Modbus RTU signal. The QE-Current-485 can also accept inputs from RTD and NTC temperature sensors.

The QE-Current-485 provides registers for the following values: I RMS, I AC, I DC (including maximum, minimum, and average), frequency, crest factor, temperature, and resistance. A 0-10V and 4-20mA analog output, as well as an alarm contact output, are also available. Settings are fully configurable using the free software, which can be connected via the USB port on the front of the QE-Current-485.

The Modbus current and voltage analyzer is DIN rail mountable, and both the power supply and the Modbus network can be connected via an optional T-BUS connector.
