| 摘要 |
The invention relates to a circuit arrangement for a digital switched output (2) for connecting a load that can be connected between the switched output (2) and another output (2'), said arrangement having at least one semiconductor switch (3, 4) arranged, with a clearance between contacts, between a supply voltage connection (1) and the switched output (2). The circuit arrangement is characterised in that the at least one semiconductor switch (3, 4) is connected to the switched output (2) via an inductance (6), wherein a connecting node between the at least one semiconductor switch (3, 4) and the inductance (6) is connected to the other output (2') via a free-wheeling element. The invention also relates to an output module for automated control comprising a circuit arrangement of this type and to a test method for a circuit arrangement of this type. |
