RS232 to RS485/422
Active Digital Isolated Serial Converter
Uses SP3232EEN and SP485EEN chips, provides stable communication with embedded galvanic isolation, lightning, and ESD protection. An ideal choice for industrial control equipment and applications with high communication requirements.
Key Features
- Embedded SP3232EEN and SP485EEN chips. Fast communication, stable and reliable, better compatibility
- Stable transmission at 300–921600 baud rate
- Built-in monolithic power isolation, provides stable isolated voltage, no additional power supply needed for the isolated terminal
- Built-in monolithic digital isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
- Built-in TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning and ESD protection
- Built-in resettable fuse and protective diodes, provides stable output current/voltage, overcurrent/overvoltage protection, improves shock resistance
- Built-in 15 kV ESD protection and 600 W lightning and surge protection
- Built-in 120 Ohm terminal resistor on the RS485/RS422 interface, disabled by default, configurable by switch
- Built-in terminal power block, allows a wide range of 5–36 V DC input voltage
- 3 LED indicators for power and transceiver status
- Industrial ABS rail-mount housing design, compact, easy to install, and cost-effective
