Modbus Current and Voltage Analyzer

General Description

The QE Current 485 from Qeed is a Modbus Current and Voltage Analyzer which can convert most outputs from AC/DC current and voltage sensors such as Current Transformers, Voltage Transformers, Rogowski Probes, 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 I RMS, I AC, I DC also maximum, minimum, average, frequency, crest factor, temperature, and resistance. A 0-10V and 4-20mA output are also available along with an alarm contact output. The settings are fully configurable with the free software which can be connected to the RS485 network.
The Modbus Current and Voltage Analyzer can be mounted on a DIN rail, and power and Modbus network can be connected to via an optional T-BUS connector.
