Crouzet Gordos GA5-6A25 solid state relay, input 90-280VAC, load 24-280VAC 25A, SPST-NO

Solid-state relays (opto-couplers) are used as an interface between different signal levels or to isolate one signal from another. Opto-coupler is similar in function to a relay. The modules are often used to enable the low voltage outputs of PLC's to control higher voltage and current loads. For example, a load voltage can be even 250 V and it will be still completely galvanically isolated from the PLC.

Opto-couplers have the following qualities:

• Long life
• No mechanical wear and tear (solid state operation)
• Silent operation
• No contact bounce

Some examples of optocoupler applications:

• Control of DC loads
• Application with electrical isolation
• To convert an NPN output into a PNP output
• To convert an PNP output into a NPN output
