Waveshare RS232 To RS485 Converter (B), Active Digital Isolator, Rail-Mount Support, 600W Lightningproof & Anti-Surge, Multi-Isolation Protection

• Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal.Stable transmission at the rate of 300~115200bps
• 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 suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
• 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.Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
