The BPI‑55 interface converter is designed for:

• 🔄 Bidirectional electrical signal conversion between RS‑232C and USB interfaces;
• ⚡ Operation in asynchronous data transfer mode, compatible with most industrial controllers, recorders, and sensors;
• 🛡 Galvanic isolation between the industrial communication line and the PC, protecting equipment from potential differences and transient processes;
• ✅ Reliable data exchange between the PC and industrial devices without the need for a hardware COM port.

When connected to a computer, the device creates a virtual COM port, allowing the use of existing software (SCADA systems, configurators, monitoring systems) without modifications or additional adaptation.

Main Functions:

• 🔄 Mutual signal conversion RS‑232C ↔ USB;
• ⚡ Automatic data direction detection;
• 🛡 Galvanic isolation of interfaces, protecting the PC and equipment from surge voltages and leakage currents;
• 💻 Virtual COM port support, compatible with all standard serial communication software;
• 🔋 Powered via USB, no external power supply required.
