A single DPDT ready assembled relay module mounted on a small PCB. All connections are made via screw terminals and it has LED indication to show when the relay is activated.

The relay operates from a DC voltage source. With diode protection for incorrect polarity connection and a clamping diode installed across a coil, this unit has many uses. If you are switching inductive loads, provision has been provided to fit a varistor across both sets of the normally open contacts. The relay boards can be secured via four M3 fixings or a suitable DIN rail housing is available.

These relay modules are ideal to interface with burglar alarms, fire detection systems, entry exit access systems and model makers.
