RS232 Female Port to RS485/422 Active Digital Isolated Converter

This female converter is equipped with SP3232EEN and SP485EEN chips, providing fast, stable, and reliable communication with improved compatibility. It supports stable transmission rates ranging from 300 to 921,600 bps. The onboard unibody power supply provides stable isolated voltage without the need for an extra power supply at the isolated terminal. Additionally, it features unibody digital isolation to enhance signal integrity, offering high reliability and strong anti-interference capabilities with low power consumption. An onboard Transient Voltage Suppressor (TVS) is also included, protecting against surge and transient spike voltages in the circuit, making it lightning-proof and resistant to electrostatic discharge. We also have the same converter but with a male port instead. Features

* Onboard SP3232EEN and SP485EEN chips. Fast communication, stable and reliable, better compatibility

* Stable transmission at the rate of 300~921600bps

* Onboard unibody power supply isolation, provides stable isolated voltage, and needs no extra power supply for the isolated terminal

* Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption

* Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic

* Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provides over-current/over-voltage proof, improves shockproof performance

* Onboard 15KV ESD isolation protection and 600W lightningproof & anti-surge protection

* Onboard 120R terminal resistor on the RS485/RS422 interface, disable by default, configurable by jumper
