Description
Overview
GAOTek dry contact signal relay LoRa gateway is an industrial-grade device designed for transmitting switching signals through LoRa for wireless relay equipment. It supports both DIN rail and wall mounting, offering IP40 protection with a wide operating temperature range of -40 °F to 185 °F (-40 °C to 85 °C). This device features an ARM Cortex-M4 processor, LoRa spread spectrum technology, and supports various networking modes like star and mesh. Additionally, it is equipped with dual DC or AC power supply options and high-receiving sensitivity.
Features
- Adopts ARM Cortex -M4, main frequency 192 MHz processor
- Terminal using LoRa spread spectrum technology for wireless data transmission, providing users with fully transparent data transmission mode. Support star, mesh network and other modes of networking, in the same network with on-demand, broadcast, multicast and other communication modes
- -139dbm high receiving sensitivity, super anti-jamming ability, adjustable transmitting power
- ISM free frequency band, no need to apply for frequency utilization fee, default 490M, avoiding 433M crowded frequency band
- Support a total of 8-way switching DI and DO; DI supports dry node input mode, DO supports dry contact output and pulse output (wet contact) two modes
- Device A detects the switching data and transmits it to device B through LoRa transmission, and the relay output of device B is the same as the switching status detected by device A
- There is a switching volume open and closed indicator status indication for each channel; input switching volume open and closed are automatically detected
- The DIP switch can be used to set the normally open and normally closed status of the output switching quantity when the LoRa wireless signal is not energized
- Supports 1 channel 100Mbps Ethernet; Ethernet supports 10/100base-T(X) adaptive Ethernet interface; supports auto-negotiation (Auto-Nego full half duplex) supports automatic crosswire detection (MDI/MDIX)
- Support web server, Windows configuration tool and other forms of configuration, support SNMP network management
- Support internal isolation, redundant dual power input; anti-reverse connection protection
- The power supply supports overload protection; meets the requirements of industrial level 4 electromagnetic compatibility; super lightning protection: lightning strike, can resist induction high voltage, anti-surge, etc
- Fanless high-efficiency heat dissipation
- Fanless high efficiency heat dissipation, reduce repair time
- Anodized aluminum alloy shell, IP40 protection level, able to withstand the test of harsh environments
- Rail or wall-mounted installation
