• Converts RS232 Signal to RS485 Communication
• Industrial-Grade Stable Data Transmission
• Supports Long-Distance Communication
• DB9 RS232 Interface with Screw Terminal Output
• No External Power Required (Model Dependent)
• Compact & Easy Installation Design
The RS232 to RS485 Converter is a reliable serial communication adapter designed to convert standard RS232 signals into RS485 signals for long-distance and multi-device communication.
It is widely used in industrial automation, CCTV systems, access control, PLC communication, and data acquisition systems where RS485 networking is required.
The module features a DB9 RS232 connector on one side and a screw terminal RS485 output (A+, B-, GND) on the other side for secure and stable wiring.
RS485 communication allows longer cable distances and better noise immunity compared to RS232, making this converter ideal for industrial and commercial environments.
Its compact and durable design ensures stable performance in control panels and embedded systems.
