Note
Maximum load current from the 24 VDC auxiliary voltage and the digital outputs
The total load current through terminals 2, 3, 6, 7 at X221 and X222 of the 24 VDC auxiliary
voltage together with the digital outputs is protected by an internal 4 A fuse. A continuous
current of 3 A in total through this fuse must not be exceeded. In your application, dimension
the total load currents from the eight digital outputs and the terminals of the 24 VDC auxiliary
voltage accordingly.
