Safety Considerations
The Monitored Guarded output modules are TÜV certified to
Risk Class 5 for safety critical outputs. The modules are
approved for de-energize to trip safety critical outputs in
single or dual module configurations.
The modules are also approved for energize to trip safety
critical outputs in dual module configuration, but only if the
fault name variables are configured and used to automatically
alarm and annunciate the detection of load/fuse faults to plant
operations personnel.
