24vdc 4PDT relay with free wheeling diode

Brand name(s) : Comat Releco Group

Features

• Freewheel diodes (also known as a snubber / suppressor diode) are used across inductive components such as relay coils to prevent voltage spikes when the power is turned off. When the coil is disconnected from an electromagnet, peaks of inverse voltage appear at the terminals which can reach very high values. These pulses can be transmitted down the line associated with the coil and could possibly affect other components. In the case of a relay being operated by such devices as transistors, triacs, etc; it may be necessary to protect against transients
