EBYTE Isolated one-to-multiple RS485 Repeater

With the popularity of electric vehicles, smart grids are building compatible charging networks to achieve efficient distribution and management of energy. Smart grids that integrate traditional power grids with advanced communication technologies pave the way for building a more efficient, environmentally friendly and reliable energy system. RS485 repeaters can highly integrate modern advanced sensor measurement technology, communication technology, information technology, etc. with physical power grids, which helps to improve the management level, work efficiency, power grid reliability and service level of power companies.

E810-R12/E810-R14/E810-R18 is an isolated repeater (HUB) for 1-channel RS485 to 2/4/8-channel RS485 launched by Ebyte. RS485 repeaters are communication devices that support 1-channel RS485 master device and 1-channel or multiple-channel RS485 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.

RS485 Repeater Main features

No packet loss

Supports communication between one RS485 master device and one or more RS485 slave devices, and the slave communication port supports up to 32 nodes. The cached RS485 hub has a 5K cache per channel, and no packet loss.

Multi-host gateway

Multi-host gateway: allows multiple hosts or devices to communicate with the external network through the same gateway, which can adapt to more variable work requirements.

E810-R41 and E810-R21 support multi-host gateway mode.

Wide voltage power supply

The power supply supports DC 9-40V wide voltage input, with overcurrent and reverse connection protection.

Isolation + protection

The communication and power supply between the master and slave interfaces are completely isolated, and the power supply signal between the host interface and the slave interface is completely isolated. The signal interface has static electricity, lightning strike, and surge protection.

The circuit is designed according to the EMC level 3 standard, with 1.5KV isolation voltage, 4KV electrostatic protection contact discharge, 8KV air discharge, and 1KV differential mode and 2KV common mode lightning surge protection, which can effectively isolate the damage caused by lightning and static electricity to the equipment.

High-speed transmission

The host interface data can be sent to all slave interfaces at the same time, and the slave interface data can be sent to the host interface in time-sharing. Using super anti-interference and high-speed isolation devices, the baud rate can reach up to 230400bps.

No configuration is required, it can be used immediately.

Application scenarios

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.

• Building automation and smart home

In building automation systems, RS485 repeaters can be used to connect and manage various smart devices, such as thermostats, security systems, lighting controls, etc., to achieve centralized management and control.

• Traffic management system

In intelligent traffic systems, RS485 repeaters can be used to connect traffic lights, cameras, vehicle detectors and other equipment to achieve real-time monitoring and management of traffic flow.

• Video surveillance system

In large-scale video surveillance projects such as "Safe City", RS485 repeaters can ensure the accuracy and real-time nature of data transmission, especially in remote monitoring scenarios, they can ensure stable transmission of video data.
