MXA143

The MXA143 differs from standard circuits in that when it detects light, the relay activates, and when it gets dark, the relay remains active for a set period. This circuit is suitable for applications where turning on a light also activates other devices, such as a fan in a bathroom. When the bathroom light is turned on, this circuit activates. When the light switch is turned off, the bathroom fan continues to run for the pre-set time to remove odors.
