Ebyte E810-R18 Industrial Grade 1-channel RS485 to 8-channel RS485 Isolated Repeater HUB

Ebyte E810-R18 Industrial Grade 1-channel RS485 to 8-channel RS485 Isolated Repeater HUB

E810-R18 is an isolated repeater (HUB) for 1-channel RS-485 to 8-channel RS-485 launched by Ebyte. RS485 hub is a communication device that supports 1-channel RS-485 master device and 8-channel RS-485 slave devices. Photoelectric isolation technology is used to protect the master and slave devices from interference. No configuration is required, and transparent data transmission between the master and slave interfaces.

This product is suitable for comprehensive RS485 communication systems such as automation control systems, monitoring systems, alarms, access control systems, IC card charging, meter reading, one-card pass, parking lot charging, etc.

Datasheet

Features

• The power supply supports DC 9-40V wide voltage input and has over-current and reverse connection protection
• Supports communication between one RS485 master device and one or more RS485 slave devices
• No configuration required, ready to use
• The host interface data can be sent to all slave interfaces at the same time, and the slave interface data is sent to the host interface in a time-sharing manner
• The signal interface is protected against static electricity, lightning strikes, and surges.
• Communication and power supply are completely isolated between the master device and slave device interfaces The power signal between the host interface and the slave interface is fully isolated
• Using super anti-interference and high-speed isolation components, the baud rate can reach up to 230400bps
• The slave communication port supports a maximum of 32 nodes
