8 Port Digital Input/Output LoRa Gateway (Point-to-Point, Transparent Transmission)

This is a LoRa transparent transmission device for 8 channels digital input/output. It has an IP40 protection rating and is specifically designed as a wireless relay device to transmit digital signals through LoRa. This wireless gateway utilizes an industrial-grade high-performance 32-bit communication processor with an embedded real-time operating system (OS) as the software platform. It can be installed using a 35mm DIN rail or wall-mounting method, catering to different application environments.

● The device adopts an ARM Cortex-M4 processor with a frequency of 192MHz.

● It serves as a LoRa terminal for wireless data transmission, providing users with a fully transparent data transfer mode. It supports various network topologies such as star and mesh networks, enabling multiple communication modes including unicast, broadcast, and multicast within the same network.

● With a high reception sensitivity of -139dBm, it possesses strong anti-interference capability, and the transmission power is adjustable.

● It operates in the free ISM 430M-490M frequency band, eliminating the need for frequency usage fees. The default frequency is 490M to avoid the congested 433M band.

● It supports a total of 8 channels of DI and output DO. The DI supports dry contact input mode, while the DO supports both dry contact output and pulse output (wet contact) modes.

● Device A detects the switch data and transmits it to Device B using LoRa transmission. Device B’s relay output matches the switch status detected by Device A.

● Each channel has indicator lights to indicate the open and closed states of the digital input/output. The input switch status is automatically detected.

● The DIP switches can be used to set the normally open and normally closed states of the digital output when there is no LoRa wireless signal connection.

● It supports an Ethernet port with 10/100Base-T(X) auto-adaptive interface, supporting auto-negotiation (full and half duplex) and auto MDI/MDIX crossover detection.

● It supports various configuration methods such as Web Server and Windows configuration tool, and also supports SNMP network management.

● When powered by dual DC power (5.08 wiring terminal):
  ● It can be powered by a wide range of DC voltage from 9-70V or AC voltage from 7-55V. The power supply automatically detects the polarity, eliminating the need to differentiate between positive and negative poles during installation.
  ● It supports internal isolation, redundant dual power inputs, and provides reverse connection protection.

● When powered by AC power (3-pin AC socket):

  ● It supports AC voltage from 85-265V or DC voltage from 110-300V, providing a wide input voltage range.

● The power supply features overload protection and complies with industrial-grade electromagnetic compatibility requirements. It offers exceptional lightning protection, high-voltage induction resistance, and surge protection.

● The device operates without a fan, ensuring efficient heat dissipation and reducing repair time.

● It is housed in an anodized aluminum alloy enclosure with an IP40 protection rating, capable of withstanding challenging environmental conditions.

● It can be installed on a DIN rail or wall-mounted.

● Wide temperature range: Operating temperature from -40°C to +85°C.

● It has passed 100% burn-in testing.
