SITOP PSE202U
SITOP redundancy modules provide additional protection from failure of the 24 V
supply. The redundancy module continuously monitors two identical power supply
units. If one unit fails, the other one automatically supplies the power. Additionally,
a signal is sent via a signal contact that can be evaluated by a controller, PC, or
control system.
You can find detailed information here:

Alternatively, the PROFINET-capable PSU8600 power supply system with one
output and additional monitoring functions can also be used.
