NB-IoT RS485 & AUX In / Out Gateway

  • NB-IoT Wireless data link provide stable data stream.
  • Wide voltage operation for Industrial applications.
  • Multi-Interface support RS-485 / Analog or Digital Input / Digital Output.
  • AUX Power output for general purpose such as plug-in sensor, or other sub system.
  • Resist the water, dust, temperature and shock and meet with the IP68 standard.
  • Analog Input support 0~10 V / 4~20mA / ADC.
  • Digital Output support PWM / Latch Mode.

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.
