NShi E90-DTU 900SL33 LoRa Radio

The NShi E90-DTU(900SL33) is a new LoRa wireless digital radio operating at 868.125MHz and 915.125MHz. It delivers up to 33dbm transmit power with multi-level adjustment and supports the global license-free ISM bands. The unit offers RS485 and RS232 serial interfaces for integration into industrial networks.

Suits Modbus systems needing long range

This radio suits engineers building Modbus networks that require up to 16km line-of-sight range and 240-byte packet support. It fits installations needing 8V to 28V supply flexibility, AES data encryption, and automatic relay hopping. Buyers who need Ethernet, Wi-Fi, or cellular backhaul should look at other products.

Deciding spec: 33dbm output at 900MHz

The 33dbm (2W) output at 900MHz determines link budget and regulatory compliance for your region. Verify that 868.125MHz or 915.125MHz operation matches local spectrum rules before purchase. The RS485 and RS232 ports define the host interface.

Highlights

  • Up to 16 km range under ideal conditions
  • 33 dBm output power with multi-level adjustment
  • RS232 and RS485 serial interfaces included
  • AES data encryption with configurable packet length
  • Operates on license-free 868.125 MHz and 915.125 MHz bands

Questions about this item

What range can I expect from the 16 km figure once the unit is installed in a real machine?

The 16 km figure applies under ideal conditions; actual range depends on terrain, obstacles, antenna height and local RF noise, so typical installations achieve less.

Which interfaces do the RS232 and RS485 ports use and what do they cap in practice?

The module provides both RS232 and RS485 serial interfaces for transparent data transfer; throughput is limited by the 240-byte maximum packet size and the configured LoRa air data rate.

What does the unit need to fit and mount in an enclosure?

It operates on 8–28 V DC, draws up to 2 W transmit power, and uses standard serial connectors, so it fits in a DIN-rail or panel enclosure with a suitable power supply and antenna feed-through.
