WAYJUN Hot product:  Industrial grade RS-232 turn RS-485 isolation module 

product description:

WJ101 is a industrial-grade RS232 revolutionary RS485 isolation converter developed by Vunduri Technology. The isolation converter is used to convert the RS232 signal to the RS485 signal, and the data achieves transparent transmission, the communication is stable and reliable, and the industry is relatively high.

WJ101 series includes power conditioning, RS232 interface communication and RS485 interface communication. Wide range is 8-32VDC, the power supply is common to the RS485, and is isolated from the RS232 interface 3000V, and the power supply has anti-reverse protection function. RS485 communication interface high anti-interference design, ± 15kV ESD protection. The product is designed according to industrial grade standards, operating temperature range - 45 ° C ~ + 85 ° C.
