The Labom PG2 units are switching amplifiers for the connection of inductive contacts. Unintended switching signals of the inductive contacts (which may well be created by vibration within immediate reach of the switching point) are largely reduced by a fail-delay time. Due to their contact free way of switching, to their switching safety and long service life, inductive contacts are particularly useful for industrial applications. The relay output switches as a potential-free  changeover contact (one per channel). It can be used, for example, for actuating control devices. Options See data sheet
