Industrial USB to RS232/RS485/RS422/TTL converter Waveshare 23996

Waveshare 23996 FT232RNL USB to RS232/485/422/TTL – Industrial Isolated Converter

Waveshare 23996 is a high-quality industrial isolated digital converter based on the original FT232RNL, which provides reliable and fast signal conversion between USB and serial interfaces (RS232, RS485, RS422, TTL). With a high level of isolation, protection and stable connection even in harsh environments, this multifunctional device is ideal for applications in industrial control and high-performance communication systems.

Key features and benefits

• Original FT232RNL chip: Provides fast and stable data transmission with high compatibility with various devices and operating systems (Mac, Linux, Android, Windows).
• Multi-interface conversion: Support USB signal conversion to RS232, RS485, RS422 or TTL, allowing you to work with multiple devices and different types of interfaces simultaneously.
• Power and Signal Isolation: Built-in unitized power isolation provides stable voltage without the need for an additional power source, and digital isolation guarantees a high level of protection against external noise and electrical interference.
• Surge and surge protection: The built-in TVS (Transient Voltage Suppressor) effectively reduces the risk of damage from surge voltages, and protection is provided by a self-recovering fuse and protection diodes.
• Automatic, lag-free transceiver circuit: Provides instant data transmission and reception between the computer's USB port and the device, ensuring smooth operation even at high transfer speeds (from 300bps to 3Mbps).
• TTL level setting: The built-in voltage translator allows you to select TTL level (3.3V or 5V) using a switch, ensuring compatibility with different logic levels.
• Status indicators: Three LED indicators (PWR, TX, RX) allow you to easily monitor the power and data transmission status, which is convenient for diagnostics and debugging.
• Industrial Metal Housing: The rugged aluminum housing not only protects the internal circuitry, but also supports wall or rail mounting, which is essential for operation in industrial environments.
