Original 8 x AA battery holder with 5.5mm/2.529mm Plug and On/Off Switch – PartsCountry

Description

This USB to 8-channel converter is made for easy communication with multiple RS485 devices via a single USB port. Power is supplied through a USB Type-C port, and it also has a reserved 5V-36V DC terminal for auxiliary power input, providing flexibility for various setups. It also supports Win11/10/8.1/8/7, Raspberry Pi, macOS, Linux, Android and others.

This converter has unibody power supply isolation and digital isolation, providing high reliability, strong anti-interference, and low power consumption. Additionally, it includes a built-in TVS (Transient Voltage Suppressor) for protection against surge voltage and transient spikes, making it lightning-proof and anti-electrostatic for improved durability and safety in industrial environments.

Features

• USB to 8-channel RS485, convenient for expanding multiple RS485 industrial serial devices.
• Direct power supply via Type-C port, with reserved 5V~36V DC wide voltage screw terminal for auxiliary power input.
• Unibody power supply isolation, provides stable isolated voltage.
• Unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.
• TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.
• Self-recovery fuse and protection diodes,the current/voltage stable outputs, provide over-current/over-voltage proof and improve shockproof performance.
• Built-in 120R terminal resistor on the RS485 ports, configurable via jumper for flexible switching.
• LEDs for indicating the power, device configuration status and transceiver status.
• Rail-mount case design, support stackable combination, easy to install and safe to use
