15 Digital output module XN-322-12DO-P17
XN-322-12DO-P17 digital output modules feature 12 short-circuit proof digital
outputs that are organized into three groups. The supply voltage for each
group is monitored for undervoltage.
In accordance with the safety requirements set forth by the Institute for
Occupational Safety and Health of the German Social Accident Insurance
(IFA), the outputs' primary side (+5 V) is isolated from the secondary side
(+24 V) with optocouplers (as required for class 3, pollution degree 2).
In addition, optocouplers are used in the monitoring circuit for the supply
voltage for each channel group in order to isolate the 24 V on the primary
side from the 24 V on the secondary side.
0 V / GND potentials and
are connected to each other.
