- Commodity name: HL485D Modbus Device
Frequency bands: 370–590 MHz, 740–1180 MHz
Overview
Herald Datanetics Ltd,(HDL)introduces a Sub-1GHz with Two Channels RS485/422/Modbus module to adopt long-range communication with conventional RS485 Devices. lt is installed in an industrial grade housing ME22.5 which is a DlN Rail mounted housing.
The Sub-1GHz band is a low-power long-range wireless transceiver module using ChirploT™ technology. lt adopts half-duplex wireless communication. There are different operating frequency band; they are 433MHz and 868MHz. The major advantage of HL485D is with high anti-interference, high sensitivity, low power consumption and ultra-long transmission range.
The industry-leading link budget, along with the -143dBm sensitivity and the ~20dBm maximum RF TX output power makes this module the best option for long-range transmission and extremely high reliability applications.
ChirploT™ : This series of chips and platforms are fuly owned by Panchip as unauthorized frequency band low-power wide area loT technology with independent intellectual property rights
The Sub-1GHz with Two Channels RS485 module with a maximum of 500 Modbus devices is poised to play a pivotal role in the following areas:
Industrial Automation
Enables reliable communication between PLCs, sensors, and control systems in largescale industrial setups. Reduces wiring complexity and costs while improving scalability.
Smart Agriculture
Facilitates long-range data transmission for soil sensors, weather stations, and irrigation systems. Enhances efficiency and precision in agricultural operations.
Smart Cities
Supports loT applications such as smart lighting, waste management, and environmental monitoring. Provides a cost-effective solution for city-wide connectivity.
Energy Management
Ideal for remote monitoring and control of energy systems, including solar panels and smart grids. Ensures efficient energy distribution and reduces operational costs.
Main Features
