Isolated RS232 To RS485/422 Converter - DB9 Male Port With SP3232EEN/SP485EEN Chips, 300-921600bps

About This Product

Attention tech professionals and industrial equipment users! This isolated RS232 to RS485/422 converter is the reliable solution you've been looking for for your serial communication needs. Featuring high-quality SP3232EEN and SP485EEN chips, this converter ensures fast, stable communication with better compatibility than many cheaper alternatives. What really sets it apart is the built-in galvanic isolation - with both power supply isolation and digital isolation that provides high reliability, strong anti-interference capabilities, and low power consumption. The transmission rate is seriously impressive, ranging from 300 all the way up to 921600bps, and the RS485/422 transmission distance can reach up to 1.2km! But wait, there's more protection features - we're talking TVS (Transient Voltage Suppressor) for surge protection, 15KV ESD isolation protection, 600W lightningproof and anti-surge protection, plus self-recovery fuses and protection diodes. This thing is built to handle tough industrial environments! The DB9 male port makes connection straightforward, and there's even a 120R terminal resistor on the RS485/RS422 interface (disabled by default but configurable via jumper). The power supply screw terminal accepts a wide 5V~36V DC input range, adding to its versatility. Whether you're working with industrial control equipment, need to expand communication nodes, require long-distance data transmission, or just need reliable serial conversion with maximum protection, this converter delivers professional-grade performance. It's the kind of specialized equipment that makes tech installations so much more reliable and worry-free.
