The AG-831 is a Gateway dedicated to work with central controlling and monitoring systems. It support two-way communication with server through 4G LTE/GSM or Ethernet. It has inbuilt timer with 10 ON/OFF schedule within 24h, auto configurable sunrise/sunset timer based on geolocation and has 3 independent relays. Every output can be controlled by separate time schedule. Gateway has isolated Modbus RTU interface to communicate with energy meters, PLCs and other Modbus devices. Can be configured by: internal website, SMS, string from server and configuration file loaded in predefine URL. For accurate time and location it has GPS and RTC. This is updated version of AG-811.
