WW-5C20 is a Narrowband IoT (NB-IoT) to RS-485 outdoor wireless gateway.
It connects to the established mobile network devices more simply and more efficiently and transmits low and intermittent data securely and reliably.
WW-5C20 provides the RS-485 MODBUS RTU industrial interface that connects to the existing industrial control host (ex.. PLC).
Analog inputs and digital inputs/outputs support external sensors to connect and trigger external devices.
Supply 5V DC/200mA output power for use in external subunits, which is much suitable as the basic equipment for the industrial Internet of things.
