NB-IoT RS485 & 5 Ports AUX In / Out Gateway (with Redundant Battery)


  • 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 / 0~20 mA / 4~20 mA / ADC (0~10 V).
  • Redundant battery inside.

WW-5D2B 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-5D2B provides the RS-485 MODBUS RTU industrial interface that connects to the existing industrial control host (ex. PLC).
Up to 5 Ports Analog inputs and digital inputs/outputs support external sensors to connect and trigger external devices.
Supply 5 independent 10V DC/50mA (Main Port up to 100mA Max.) output power for use in external subunits, it is ideal for multiple sets of equipment in the Industrial IoT.
A redundant battery is provided internally, and when an external power supply fails, an emergency notification can be sent to the center for repair.
