RS232 TO RS485 (B)
without LED indicator
RS232 TO RS485 (D)
with LED indicators
- Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
- Stable transmission at the rate of 300~115200bps
- Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
- Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective

RS232 To RS485 Conversion
Access to a host, PLC or other devices with RS232 port, the RS232 can be converted to RS485 port for point-to-point half-duplex communication with external RS485 devices.
Access to a host, PLC or other devices with RS232 port, the RS232 can be converted to RS485 port for point-to-multipoints half-duplex communication with external RS485 devices.
The RS232 TO RS485 converter can be widely used for point-to-point, point-to-multipoint, long distance cascaded communication network between two hosts, or between host and MCU/Peripheral. It also can be used in the application scenarios that require RS232 to RS485 conversion such as Industrial Automation and IoT.
