Available for order.

The BPI‑485 interface converter is designed for:

🔄 Bidirectional signal conversion between RS‑232 and RS‑485 interfaces;
✅ Connecting RS‑232 devices (personal computers, barcode scanners, electronic scales, etc.) to an RS‑485 industrial communication network;
🛡 Ensuring reliable and safe data transmission thanks to galvanic isolation between interfaces.

The device automatically detects the data transmission direction on the RS‑485 line, simplifying operation in half‑duplex industrial networks.

Main Functions

🔄 Signal conversion RS‑232 ↔ RS‑485;
⚡ Automatic data direction detection for RS‑485 half‑duplex mode;
🛡 Galvanic isolation of interfaces, protecting equipment from surges and potential differences;
🔋 Powered from an external 24 V DC source, ensuring stable operation under industrial conditions.

Electrical and Functional Specifications

⭕ Interfaces:
- RS‑232 (asynchronous mode, standard ±12 V signal level)
- RS‑485 (two‑wire connection, half‑duplex)
⭕ Galvanic isolation: between RS‑232 and RS‑485
⭕ Power supply: 24 V DC
⭕ Data rate: up to 1 Mbit/s
⭕ Operating mode: asynchronous, automatic data direction detection
