The signal light is designed for use in light signal systems (e.g., lock systems, movable bridges on inland waterways, etc.). The use of safety-related autonomous monitoring functions ensures high availability. Only components that conform to the industry standard are used for the monitoring functions. The signal light is available in various light colors. You can manage the signal light from the application program using a controller from Phoenix Contact. The communication interface provides you with a large amount of diagnostic and status information.
