- 3 independent NO/NC outputs
- Isolated RS485 and digital inputs with SMS alerts
- Internal website for configuration
The AG-811 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 with NO/NC outputs. 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.
