Industrial-grade lightning-proof high-load four-port RS485 hub
WM-6504-B is an industrial general-purpose four-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-6504-B’s RS485 hub: Data is sent to each branch (CH A, CH B, CH C, CH D) 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 Primary/secondary RS485
- signal: signal group T/R+(A) T/R-(B) CH A CH B CH C CH D–copper screw terminal
- Number of terminals supported: Each group can be connected to 128 RS485 nodes; the theoretical value is 512 nodes in four 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 one signal is short-circuited, it will play a protective role, but it cannot be in a short-circuit state for a long time.
- Power consumption: 180Ma@9V 2.
