Abstract
The invention relates to an output circuit for an output module for switching at least one connected load. The task of the invention is to present a circuit for output-side switching of at least one connected load, especially a circuit that also satisfies the standards DIN EN 954-1 or IEC 61508.The invention proposes an output circuit for an output module for switching at least one connected load, especially an inductive load, which is distinguished by a one-channel peripheral terminal (PA) for connecting the one or more loads and which comprises at least two driver modules (101; 102), especially FET transistors, connected in series between a power-supply voltage and the peripheral terminal, wherein each of the driver modules is connected to a logic unit assigned to the output module for controlling the driver modules via a separate control channel (OUT_LK1, IC10; OUT_LK2; IC20).
