Industrial USB TO 4CH RS485 Converter, Multi-Layer Protection, Multi-System Support, Aluminum Alloy Enclosure, Supports Wall-Mount & Rail-Mount
Industrial USB TO 4CH RS485 Communication Module
Features At A Glance
- USB extend to 4CH RS485, allows simultaneous and independent communication for each channel
- 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 stable current/voltage output, provides over-current/over-voltage protection, improves shock resistance performance
- Onboard 120R termination resistors for RS485, enabled/disabled via DIP switch
- Aluminum alloy enclosure with sandblasting and anodic oxidation surface, solid and durable, well-made
