(Silicon Chip July 2014)
A simple but versatile device to switch a relay when an input crosses a preset threshold. It takes the output of an analogue sensor, battery voltage or other varying voltage and switches power to a fan, warning light or similar when a preset voltage is reached. Suitable for use with 5, 12 or 24V power supply. Ideal for preventing overcharging in batteries. Trigger can be on high or low voltage.
Includes S 4190D 5A relay. 107 x 61mm.
