Custom Specific Solutions

The lamp detector LD-24V is checking the connected lamps during they are switched off. If a defect filament or missing lamp is detected, the according alarm contact is switching. If the supply voltage falls below the minimum value the POWER alarm is switching. At faultless lamp the according LED is lighting. Due to the galvanically isolations a wide range of circuits may be designed.
