SATEL ISO-RS485 Isolatore galvanico RS-485

The SATEL ISO-RS485 is a galvanic isolator designed for RS-485 data buses, providing reliable isolation and protection in security, automation, and industrial systems. It ensures signal integrity and prevents ground loops and potential differences between connected segments.

Advantages

Galvanic isolation up to 1 kV protects equipment and data from voltage spikes and ground loops. Supports data rates up to 115.2 kbps, ensuring fast and reliable communication. Compact DIN rail mount design saves space in control cabinets. LED indicators for power, transmit, and receive simplify diagnostics.

Suitable for

• Security systems (alarm, access control)
• Building automation (HVAC, lighting)
• Industrial control and monitoring
• Any RS-485 network requiring isolation
