1、 Overview

1.1 Purpose

AOB19 intelligent programmable digital power meter is a new generation of programmable smart meters, mainly used for real-time measurement and indication of active power in single-phase or three-phase power lines, and remote transmission of measured power data through RS485 interface or analog transmission output interface.

1.2 Functional Features

Adopting a modular design approach, the voltage and current transformer multiplier of the full SMT production process can be freely set

One channel analog transmission output function (optional), the output can be programmed to be 0-10mA, 0-20mA, 4-20mA at will

One way lower limit alarm output or two-way switch remote control output function (optional), alarm action delay time can be set arbitrarily within the range of 0-60s

RS485 communication output function (optional), using standard MODBUS-RTU communication protocol

It can simultaneously have one analog transmission, one lower limit alarm, and RS485 communication output functions

Two or four switch status detection function (optional), combined with RS485 communication to achieve "remote signaling" and "telemetry" of switch status

Maximum and minimum value viewing function
