Industrial USB TO 4CH RS485
Stable Transmission | Multi Devices | Multi Systems
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
