3.3.1.

SPS 24-1

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.
