SW820-PCB Compatible Replacement Board for CAME ZA3

The SW820-PCB is the ideal electronic control board to replace the ZA3 CAME, which is no longer in production.
100% compatible, it allows you to keep the original transformer and radio receiver (both 30.9 MHz and 433.92 MHz) without changing connections or wiring.

Why Choose SW820-PCB

• Direct replacement: identical terminal blocks and programming similar to the ZA3

• Versatility: controls 1 or 2 electromechanical motors at 230 V, underground or external

• Compatibility: Supports existing AF CAME receivers and radio controllers

• Reliability: robust electronics, overload protection and stable operation over time

Main technical data

• Number of engines: 1 or 2

• Accessory Output: 24 V AC 20 W max

• Electric lock output: 12 V AC 15 W max

• Flashing Output: 230V AC 200W

• Courtesy light output: 230 V AC 200 W

• Open gate indicator light output: 24 V AC 3 W max

• Motor force adjustment: 50 % to 100 %

• Maximum working time: 80 s

• Radio connector: Plug-in type AF CAME

• Operating temperature: –10°C ÷ +50°C

• Maximum humidity: < 95 % non-condensing

• Fuses: 5 A line – 12/24 V 3.15 A outputs

Frequently asked questions

• Does the board include transformer and radio receiver?
  No, it comes without, like the original ZA3.

• Can I use it for other automatisms?
  Not recommended, as it lacks the transformer necessary for autonomous operation.

In summary:
The SW820-PCB is the simplest and most immediate solution to give new life to automated gates with CAME ZA3 control unit, while keeping intact the compatibility and reliability of the original system.
