Phoenix contact OV-24DC/60DC/3 2904023 24V solid-state relay with 3A 1-60Vdc output

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
