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 voltage signals from magnetic pickups, transducers, and flow meters between -10 V ... 10 V with signal frequencies up to 1.2 kHz.
