Eaton Electric Z-R230/SS 265168 relay 230VAC 20A

Relays are used as an interface between different signal levels or to isolate one signal from another. Relay is similar in function to a contactor. The modules are often used to enable the 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.

Relays have the following qualities:

• Cheap
• Small size, but compared to size can still connect large currents and voltages
• Simple construction
• Does not interfere with the controlled signal besides for the contacts resistive effect (in practice no effect on anything)
• Can drive alternating current and directed current loads

Some examples of relay applications:

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