- This isolated barrier is used for intrinsic safety applications. It transfers voltage signals from hazardous areas to safe areas.The input voltage of the terminals 4 and 5 is transferred to the terminals 7 and 8. The terminals 4 and 8 have the same polarity.
It repeats 0 V ... 12 V signals from strain gauges, transducers, and inductive motion sensors with signal frequencies up to 1.2 kHz.
