Industrial-grade lightning-proof high-load two-port RS485 hub
WM-6502-B is an industrial general-purpose two-port adaptive RS485 repeater hub with a main RS232/RS485 port. It is an RS485 hub specially designed for extended RS485 transmission distance and large-capacity serial communication networks.
The working principle of WM-6502-B RS485 hub: Data is sent to each branch (CH A, CH B) through the main port. After the data is received into the branch, it is transmitted to the main port. At this time, other branches will not receive its signal.
The main physical interface and data lines of the converter are made of all-copper material to ensure the stability of communication. The special circuit design can effectively shield external interference.
- Main RS232 signal: TX RX GND (DTR DSR CTS DCD can be customized) –DB9 hole
- Primary/secondary RS485 signal: signal group T/R+(A) T/R-(B) CH A CH B–copper screw terminal
- Number of terminals supported: Each group can connect to 128 RS485 nodes; the theoretical value is 256 nodes in total for two groups
- Transmission distance: theoretical value 1.5km, tested at 9600k/s RS485
- data anti-collision protection control: DCPC
- Serial port protection: 15KV ESD at RS232 end; instant voltage suppression TVS at RS485 end, 400W protection per line
- Working temperature: -25-65℃
- Storage temperature: -20-75℃
- Working humidity: 5-95%RH
- Working power supply: 9-36 VDC 350Ma
- Overcurrent protection: When two signals are short-circuited, it will play a protective role, but it cannot be short-circuited for a long time.
- Power consumption: 180Ma@9V 2.
