The MUS‑485 interface repeater is designed for:

• 🔄 Amplifying and retransmitting RS‑485 interface signals;
• 📡 Extending communication line length beyond 1200 meters;
• ➕ Expanding the number of connected devices beyond the standard 32 nodes without signal quality degradation;
• 🛡 Improving the reliability of industrial networks by eliminating the effects of interference and potential differences through galvanic isolation.

The repeater automatically detects the data transmission direction and does not require additional signal control for operation in RS‑485 half‑duplex networks.

Main Functions

• 🔄 Automatic retransmission of RS‑485 interface signals;
