Rectangular aluminium wireless transceiver module with antenna connectors

NaSR

NaSR RS232/485/422 LoRa DC12-36V Wireless Transceiver Module

SKU CH-BHQB-2CMWB

Wireless RS232/485/422 LoRa transceiver operating on DC 12-36V for long-range industrial data links

  • Aluminium alloy housing ensures long service life
  • Point-to-point mode links two LoRa modules for two-way data exchange
  • High RSSI and strong SNR with anti-interference tech for reliable reception
  • Address and encryption functions enable secure directional communication
  • Multi-level relay networking extends range in complex environments

Industrial LoRa Transceiver

The NaSR RS232/485/422 LoRa module provides wireless serial connectivity for automation and telemetry systems. It operates on a DC 12-36V supply and interfaces with equipment through standard RS-232, RS-485, or RS-422 ports. The aluminium alloy housing protects the electronics in harsh environments. Two modules establish a transparent point-to-point link for bidirectional data exchange.

Passive Cooling and Low Draw

The sealed aluminium enclosure dissipates heat passively without fans, ensuring silent operation in control cabinets or remote sites. Power consumption remains modest across the 12-36V input range, allowing use with solar-charged batteries or limited industrial supplies. Strong anti-interference design and high receiver sensitivity maintain link integrity without increasing electrical noise or thermal load.

Replaces Wired Serial Links

This module replaces trenching or long cable runs between PLCs, RTUs, and sensors where RS-232/485/422 wiring is impractical. The jump is worth it when physical cabling costs exceed the radio hardware cost or when mobile and temporary installations demand rapid deployment. It does not suit applications requiring licensed-band reliability or throughput beyond narrowband LoRa capacity.

Questions about this item

How do I wire the DC 12-36V power and the RS232/485/422 serial lines during installation, and which step is most often missed?

Connect the supply within the 12 to 36 volt range and match each serial interface to its corresponding port; the step most often missed is confirming that both LoRa modules share the exact same frequency and address settings before powering up.

What maintenance or replacement will the aluminium-alloy transceiver need over its service life?

The aluminium alloy housing is built for long service life with no user-serviceable parts; only periodic inspection of antenna connections and power wiring is required, and the module itself is replaced only if a hardware fault occurs.

What limit appears first when the module runs continuous two-way data links at high RSSI and SNR?

Sustained operation is limited by the DC 12-36V supply stability and thermal dissipation of the aluminium enclosure; if voltage sags or heat builds up, the anti-interference performance and relay networking reliability degrade first.
