Note
An external load voltage supply can only be looped via the digital output
module DO 8
DC 24V/0.5A until the maximum current of 4 A is reached.
The maximum current load of 4 A is not protected by means of a fuse in the
module.
Spur lines are not permitted on the ET 200C except for the programmer or
the ET 200 handheld. This means that the 12-pin plug of the T connector is
always secured directly to the bus connection of a module.
