The HT501-H116 series of industrial-grade RS-485 hubs utilize high-speed optocoupler isolation for protection and feature a built-in DC-DC power isolation module. Supporting the conversion of 1 RS-485 channel to 16 RS-485 channels, these hubs are specifically designed for large RS-485 systems operating in complex electromagnetic environments, making them highly reliable and cost-effective industrial-grade transmission devices.
The HT501-H116 hub features a built-in opto-isolation module that electrically isolates the signal loops between devices at both ends, converting electrical signals into optical signals for transmission. This ensures stable communication and makes the hub widely applicable in scenarios such as highway tolling, card-swiping systems, banking automation, and power data collection.
