[Industrial Signal Conversion]This Serial Port Converter Module supports for RS232 TTL to for RS422 for RS485 conversion. Built with SP3232 and SP3485 chips for stable data transfer in industrial control setups.
[Isolated Communication Design]The Isolated Serial Port Conversion Module uses an onboard digital isolator to reduce ground potential interference and help maintain stable signal transmission between connected devices.
[Easy Wiring Setup]Standard DB9 connectors and 5.08mm detachable terminal blocks support quick plug and play installation. DIN rail mounting design with ABS enclosure fits control cabinets and equipment panels.
[Automatic Data Switching]Integrated automatic send and receive switching circuit enables communication between for RS232 and for RS485 for RS422 without manual control. Built in LEDs show power TXD and RXD status.
[Practical Application Use]Supports baud rates up to 2M bps for RS422 and RS485 based on connected devices. Suitable for PLC systems automation cabinets serial debugging and industrial communication environments.
