KEY AUTOMATION MA24 Logic Mainboard for 14A Control Unit

Product Overview

The MA24 is the logic mainboard designed for use within the 14A control unit, providing the core processing, automation logic, and safety management for 24V gate automation systems. Acting as the “brain” of the 14A, the MA24 governs motor control, safety inputs, radio communication, and advanced functions such as obstacle detection and slow-down management.

Ideal as a replacement mainboard or for maintenance and repair, the MA24 restores full functionality to compatible 14A control units, ensuring continued reliable operation of single or dual 24V motor installations.

Technical Specifications

Is this the right component for you?

The MA24 is ideal if you:

• Need to repair or refurbish a 14A control unit
• Have a faulty or damaged logic board
• Want to restore full automation and safety functions
• Are maintaining an existing 24V gate system

You may want an alternative if you:

• Need a complete control unit with enclosure and transformer
• Are using a different control board platform

ACS Team Insight

The MA24 is most commonly used when a 14A control unit enclosure and transformer are still serviceable, but the logic board has failed due to age, moisture, or electrical damage. Replacing just the MA24 is a cost-effective way to extend system life without rewiring the entire installation.

As always, confirm 14A compatibility and ensure programming access via DYL or KUBE PRO before commissioning.
