ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•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
