Primary Function

Converting The RS232 Signal Into Balanced Differential RS485 Signal
For Interface Converting, Expanding Nodes And Long-Distance Communication

Rail-Mount Support

Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely

Multiple Protection, Safe And Stable

Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard Lightningproof Diodes and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.

Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock proof performance.

Interface Introduction

Application Topology

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.

Application Examples

The RS232 TO RS485 (B) 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.
