Operation Theory

 21 

The PhotoMos relay incorporates the advantages of both a semiconductor 
and an electro-mechanical relay.  The PhotoMos relay utilizes the MOSFET 
as a switch instead of the mechanical contact. Thus the contact resistance 
remains stable through the life of the relay. Furthermore, dithering problems 
is eliminated.  

The PCI-7258 is equipped with 32 PhotoMos relays, which are all form A 
type. The load voltage can either be AC or DC. The basic wiring diagram is 
shown in figure 5 below. 

 

Figure 6:    PhotoMos relay wiring diagram  

If an inductive load is connected, the spike voltage may exceed the relay’s 
maximum rating. To protect the components, user should add a diode in the 
circuit. A typical protection circuit is shown below.
