Specification Brand : waveshare BulletPoint1 : Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal. Stable transmission at the rate of 300~115200bps BulletPoint2 : 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 interference-free, low power consumption BulletPoint3 : Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, Non-electrostatic BulletPoint4 : Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance BulletPoint5 : Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch. The onboard power supply screw terminal, allows 6V~36V DC wide range input.
