The digital output (DO) signals error messages and can be
confi gured as follows: 24 V → 0 V/0 V → 24 V.
In order to increase the switching current of the DO, the
latter may be expanded by a relay. Thanks to the contour
uniformity of Series 857, for example, a 857-304 Relay
can be snapped in next to it. This output can be quickly and
easily expanded to a switching current of 6A by simply using
an adjacent jumper (859-402).
