Ebyte E810-R21 Industrial Grade 2-channel RS485 to 1-channel RS485 Isolated Repeater HUB
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.
Features
- Power supply supports DC 9-40V wide voltage input, with overcurrent and reverse connection protection
- Supports 2/4 RS485 master devices to communicate with 1 RS485 slave device
- Can be configured through any serial port
- Supports multi-master mode (the data returned by the slave will only be returned to the corresponding requestinghost) and bidirectional pass-through mode (the data returned by the slave will be returned to all hosts)
- Signaling interfaces are protected against static electricity, lightning strikes and surges
- Complete isolation of communication and power supply between master and slave interfaces
- The power signal between the host interface and the slave interface is fully isolated
- Adopts super anti-interference and high-speed isolation devices, baud rate up to 115200bps
