3-in-1 RS232 to RS485/RS422 Converter Module with Isolation Protection - Full-Duplex RS422 & Half-Duplex RS485 2Mbps Speed 5V Powered LED Indicators Rail-Mount for Industrial Communication

Bidirectional conversion: support RS232 and RS485/RS422 interface data real-time transfer, of which RS422 supports full-duplex synchronous sending and receiving, RS485 supports half-duplex automatic switching, suitable for industrial-grade multi-device communication scenarios ^^
Isolation protection: integrated power isolation (DC/DC), signal isolation (digital isolator), TVS transient suppression tube, GDT gas discharge tube, self-recovery fuse, can resist surge, lightning and static interference, to protect the stable operation of complex environments ^^
Compatible and stable: Adopting original SP3232 SP3485 chip, the communication rate is up to 2Mbps (subject to equipment limitations), on-board 120R termination resistor pads and automatic transceiver switching circuits, no need to manually control transceiver status, optimizing the stability of long-distance transmission signals ^^
Installation and visualization: Equipped with 5.0 mm plug-and-play terminals and rail-type ABS environmental protection housing, supporting plug-and-play and flexible installation; on-board three-color LED indicators (PWR power, TXD transmit, RXD receive), real-time display of power status and data flow direction ^^
Scenario adaptation: only 5V power supply, 485/422 independent power supply design; support for indoor short distance (no grounding) and field long distance (grounding to enhance anti-jamming) transmission, suitable for industrial automation, intelligent buildings, security monitoring and other fields
