Active Low Relay Module Circuit

Relay module is required to turn on or off electrical loads which are operated by high voltage. An electronic control signal is applied to the input of a relay module and at the output, contacts switch from its normal position to another position. The supply voltage of a relay can be 5 V, 6 V,…

Active High Relay Module Circuit

Relay module is required for controlling one or more than one (AC/DC) loads by switching method. A relay is an electromagnetic switch that is commonly used in automatic control systems. DC voltage is applied to input of a relay to energize the coil inside it. If the coil is energized, the contacts at its output…
