Product Name: DC 12V 24V 8 Port RS485 Hub Repeater Serial Port Signal Amplifier 100-1000Kbps for PLC PTZ Security Monitoring

Package included:
1 PCS 8 Port RS485 Hub Repeater Module

Product presentation and description:

Power input supports DC 8~30V,One power indicator lamp, the PWR, is always on,9 Receiving indicators R 0-R 8,R0 is the indicator lamp for the hub port reception,R 1 to R 8 receives the indicator light for the distribution port,When there is data incoming, the receiving indicator light flashes, and when there is no data incoming, it does not light up. The master port is the hub port, and the slave port is the distribution port.

•Power Supply Voltage:DC 8~30V,Power supply anti-reverse connection protection
•Communication interface: RS-485
•Communication rate:100bps-1000Kbps
•Transmission medium:Two-core twisted pair shielded cable
•Way of working:Asynchronous half duplex（RS-485）
•Protection circuit: 400W surge protection, ±20KV ESD protection
•Communication interface performance:Each 485 interface can connect 256 devices
•Communication distance :The communication distance of 485 per road is increased by another 1,200 meters on the original basis
•Power supply and signal indication:Power supply / receive LED, with a total of 10 red indicators
•For all communication software, independent of the protocol, plug and play
•Size:110mm*90mm*40mm
•Weight:128.8g
•Use environment:The temperature is -40°C to 80°C, and the relative humidity is 5% to 85%
•Cascade:Supports cascading of hubs, the existing RS-485 bus has been extended to 8 high-reliability RS-485 interfaces, and 256 RS-485 devices can be connected hand in hand on each RS-485 interface at the same time
 

Common applications:
1.The application of the host computer RS485 to 8 high-reliability RS-485 interfaces.
2. The existing RS-485 bus is extended to 8 high-reliability RS-485 interfaces, and 256 RS-485 devices can be connected hand in hand on each RS-485 interface at the same time.
3.Through the hub cascade mode, the existing RS-485 bus is expanded to 15/22/36..., and 256 RS-485 devices can be connected hand in hand on each RS-485 interface at the same time.
