Universal Signal Isolator (CANBUS, UART, RS232, RS485, SPI) – 5kV Protection

Protect your systems from electrical noise and ground loops with this high-performance universal signal isolator. Engineered for industrial, automotive, and embedded applications, it provides 5kV galvanic isolation for safe and reliable communication.

This plug-and-play device isolates a wide range of common communication protocols, including CANBUS, UART, RS232, RS485, and SPI (note: I²C is not supported). With integrated ESD protection and built-in level shifting between 3.3V and 5V logic, it’s the perfect drop-in solution for robust signal integrity.

Key Features are:

• Isolates CANBUS, UART, RS232, RS485, Digital I/O and SPI
• 3 in/ 1 out and 1 in/ 3 out Signal Routing Options
• Integrated EST, EFT and Lightning Surge Protection
• Selectable 3.3V or 5V Isolate Output
• 5kV Isolation
• Plug and Play with No Configuration Needed
