1. Output circuit for an output module for switching at least one connected load, the output circuit comprising:
a one-channel peripheral terminal (PA) for connecting the one or more loads; and
at least two driver modules (101; 102) connected in series between a power-supply voltage and the peripheral terminal, wherein each of the driver modules is connected via a separate control channel (OUT_LK1, IC10; OUT_LK2, IC20) with a logic unit assigned to the output module for controlling the driver module;
wherein an output-side load can be assigned to each of the driver modules, wherein the loads can be connected in parallel with the peripheral terminal.
