USB to 4Ch Serial RS485 Converter
USB to 4Ch Serial RS485 Converter
Features:
- Extending USB to 4CH RS485, allows concurrent and independent communication for each channel
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
- Onboard RS485 output terminal 120R resistors, enabled/disabled via DIP switch
- Aluminium alloy case with oxidation dull-polish surface, CNC process opening, solid and durable, well-crafted
