Isolation

Isolation modules provide galvanic separation between interfaces and power domains, letting communication continue while protecting sensitive electronics. They are useful where ground loops, high common mode voltages or noisy power rails threaten sensors, actuators or control boards.

Variants include signal-only isolators and modules that also supply isolated, regulated power to the remote side. Key attributes are true bidirectional bus support with clock stretching, per-side voltage compatibility, isolation rating, data timing and latency, and connector or header options that affect integration. Long-term reliability and predictable behaviour under noise are important for deployed systems. Attributes to compare include isolation method, power delivery, interface compatibility and form factor.
