SEVEN Sensor Box
It is an UV protected aluminum box, including an electronic card where up to 6 different sensors can be connected and has an RS485 port output to transfer data in Modbus RTU protocol to the datalogger or Scada system. SEVEN Sensor Box communicates by Modbus RTU protocol through RS485. SEVEN sensor is compatible with many well-known datalogger brands as it is also SunSpec compliance for the necessary devices.
The Sensor Box has max. 6 inputs and 1 output connectors. Each plastic connector has a different pin number which prevents any connection confusion during site installation. SEVEN Sensor Box is designed as Plug & Run device and end user friendly operation.
