Disclosed is a large-range input circuit for digital signals in the range of extra-low voltage signals of &#x2266;120 V and in the range of low voltage signals of &#x3c;1500 V, said input circuit comprising series-connected Zener diodes that are polarized in the reverse direction, each one defining at least one switching threshold in the range of the extra-low voltage signals or in the range of the low voltage signals, and can be selected to be active by not being bridged, wherein a respective auxiliary optocoupler, which can be controlled by a microprocessor, is used to bridge the inactive Zener diode.

Large-range input circuit

The invention describes a T-shaped bus connector comprising a holding device for mechanically retaining the T-shaped bus connector on a mounting device on which the T-shaped bus connector is to be arranged, and further comprises a first and a second connecting unit for respectively producing an electrical connection to a complementary connecting unit of a device arranged adjacent to the bus connector, wherein the first and second connecting units face in substantially opposing directions and are constructed complementarily to one another, as well as a third connecting unit, oriented substantially perpendicular to the first and second connecting units, for producing an electrical connection to a connecting unit, complementary to the third connecting unit, of an electrical or electronic module, wherein data and/or power bus lines are run between all three connecting units, and all three connecting units are covered at least in part with a shielding material.
