Convertidor industrial USB a 4 canales RS485, carcasa de aleación de aluminio, circuitos de protección múltiple, soporte para sistemas múltiples

Stable Transmission | Multi Devices | Multi Systems

• 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

Onboard Resettable Fuse And Protection Diode, Provides Over-Current/Over-Voltage Proof, Improves Shock Proof Performance; Onboard Voltage Translator Circuit, With Surge Suppress And ESD Protection, Safe And Stable Communication

Supports Win7/8/8.1/10/11, Mac, Linux, Android, Etc.

The USB Signal Can Be Converted Into 4 Balanced Differential RS485 Signals And The Transmission Rate Is Stable. The Reliable Speed Is 1200~460800bps, The Transmission Distance Is About 1.2km For RS485, And About 5 Meters For USB.
