The wiring should be made according to the attached diagram.

When using inductive loads, such as relays or electro-valve coils, surge arresters should be

installed to protect the reed contacts.

With a dc supply, a diode should be used.

For an ac supply, an RC circuit can be used as shown, although a varistor (VDR) is better and is

easier to select the right value.

The VDR should have a breakdown voltage greater than 1.5 times the rms voltage.

The standard varistor ratings specify the rms working voltage for the varistor, for example a

S05K25 varistor will be for 25 V

rms

working and will have a breakdown voltage of 39 V at 1 mA.
