Smart Gateways

he SG series of smart gateways are intended to connect various equipment into communication network. The gateway has built-in two optical (IR) communication ports and the RS485 serial communication with the MODBUS protocol.

RS485 communication enables data transmission and consequently the connection of communication gateway into the RS485 network and communication with various equipment, consisting of RS485 communication (e.g. energy meters, latching switches, power monitoring devices, etc.), via MODBUS.

The SG series also consist of pulse input and temperature sensor (Pt1000) input.

The SG-W1 version is equipped with Wi-Fi communication. This type also has an alternative version with an external antenna (SG-W1A).


The SG-E1 version is equipped with Ethernet communication. Activation of Wi-Fi communication (via parameter) is also possible with this device, but in that case, the Ethernet will not be active on RJ45.
