E810-R21 Industrial-grade 2 to 1-way RS-485 hub Photoelectric isolation technology Lightning protection signal amplifier

[Data interface]:RS485

[Working voltage]:DC 9~40V

[Protection level]:Industrial EMC level 3

[Product size]:100*54*32mm

[Introduction]:E810-R21 is a 2-way RS-485 to 1-way RS-485 buffered isolation repeater launched by Ebyte. It uses photoelectric isolation technology to protect the master and slave stack devices from interference. The circuit is designed according to the EMC level 3 standard, which can effectively isolate the damage caused by lightning and static electricity to the equipment. No configuration is required, and transparent data transmission is carried out between the master and slave interfaces.
