The SPS 24-1 device serves to switch power between the main 24V DC power source and the telemechanics backup power source. Its primary function is to automatically switch the SEM SC11 controller's power supply in case of a primary power failure, ensuring uninterrupted controller operation. Additionally, it acts as a controller lockout device in the event of a primary power loss, preventing undesirable switchgear operations. This feature is crucial for maintaining continuity in challenging conditions, ensuring system reliability and efficiency.
