Why choose it

This isolator/repeater extends RS-485 networks beyond the standard 32-node limit and protects against ground loops and transient surges. Its wide input voltage range and low power consumption make it suitable for diverse industrial power systems.

Ideal use cases

• Connecting RS-485 devices in electrically noisy environments
• Extending RS-485 bus length in factory automation
• Isolating segments in building automation systems
• Protecting equipment from ground potential differences

Good to know

The unit features screw terminal blocks for secure wiring and an ABS plastic housing for durability. It operates in humidity from 5% to 95% RH (non-condensing).
