ACNSEM3L

Centrale per lanterna semaforica

The ACNSEM3L control unit is an advanced optical signaling device designed for the coordinated management of two traffic lights (2 or 3 lights each). Entirely designed and manufactured according to Made in Italy standards, this control unit is the ideal solution for access automation in contexts requiring reliability and ease of configuration. Thanks to the integrated multilingual LCD display, it allows for quick and precise programming of all cycle times, ensuring maximum industrial safety in every transit scenario.

Main applications

• Alternating one-way management on ramps and slopes: regulation of vehicle flow in low-visibility areas with customizable clearance times
• Residential and industrial gate automation: intelligent entry control via photocells or magnetic loop detectors​
• Traffic regulation in loading/unloading zones: coordination of access phases for heavy vehicles in logistics hubs
• Security systems with emergency management: absolute transit priority in case of an alarm via a dedicated input

Target clients

• Automation system installers: for the ease of wiring and immediate diagnostics via LEDs and display
• Industrial and logistics maintenance managers: thanks to the robustness of materials and the ability to handle loads up to 230V
• Parking and condominium managers: for efficient and safe management of alternating one-way traffic

Caratteristiche tecniche

• Light management: supports 2 traffic lights (2 or 3 lights each)
• Electronics: board with microprocessor and 5-language LCD display (IT, EN, FR, DE, ES)
• Operating logics:
  • On request: activation via external sensors (N.O. or N.C.)
  • Timed (cyclic): autonomous operation based on set times
  • Mixed: automatic light change with priority for detected inputs
• Board power supply: 24 Vac/dc (base version) or 230 Vac (KIT version with transformer)
• Light power supply: manages 12-24V or 230V Vac/dc loads (determined by the light input)
• Protection rating: IP44
• Working temperature: -20°C / +60°C
• Safety: dedicated emergency input (IN3) with programmable behavior
