Durite standard/mini changeover relay with diode, rated at 12V, 30/40A.

Features a diode fitted across the coil (terminals 85 & 86) to suppress voltage spikes that occur in the coil circuit when the relay is de-energised. If not suppressed, these can damage sensitive electronic components such as those found in central locking or alarm systems.

Important: +12V must be applied to terminal 86 and ground to terminal 85.  If this is reversed, the diode may be damaged.

Includes detachable metal bracket for mounting if not using a relay socket.

Type B pin layout

Sold individually.

The internal diode is great feature, it saves an external component and helps protect the relay contacts from inductive loads.
