USB to 4-Channel RS485 Converter

Overview

The USB to 4-channel RS485 converter is designed for seamless communication across multiple devices, making it an essential tool for industrial automation and data acquisition systems. This device allows simultaneous and independent communication on each channel, ensuring efficient data transfer.

Key Features

• Multi-Channel Communication: Expands a single USB connection into four independent RS485 channels, enabling concurrent operations.
• Surge Protection: Equipped with an onboard transient voltage suppressor (TVS) that mitigates surge voltages and protects against lightning strikes and static electricity.
• Current Stability: Features a self-restoring fuse along with a protection diode to maintain stable current/voltage output while providing over-current and over-voltage safeguards.
• Adjustable Termination Resistor: Includes a 120R resistor on the RS485 output terminal that can be enabled or disabled via a DIP switch for optimal performance.
• Durable Construction: Housed in an aluminum alloy shell with an oxidized matte finish, this converter is built using CNC processes for enhanced durability.
