Device SPS24-1 is used for switching power supply voltage 24 V DC.
Fig. 3.4. SPS 24-1
At the output of the device marked Out, there is the power supply from inputs In1 or In2. The voltage
at the output marked Out comes from the input In2 when it is applied only to In2. If voltages are present
at both inputs or only at input In1, the power comes from the input In1. The status of operation on the power
supply from In1 is confirmed by the voltage presence at In1_OK. An important feature of the device is
the galvanic insulation between supply circuits.
