KEY AUTOMATION CT20324 24V Control Unit

Product Overview

The CT20324 is a 24 V DC control unit designed for swing gate automation with two motors, intended for systems without encoder feedback. Supplied pre-mounted in a protective enclosure, the CT20324 delivers reliable control, advanced safety logic, and smooth gate movement for residential and light commercial swing gate installations.

Using amperometric obstacle detection rather than encoders, the CT20324 provides effective safety protection with automatic motion reversal, while keeping installation simpler and more cost-effective where encoder precision is not required.

Technical Specifications

Is this the right control unit for you?

The CT20324 is ideal if you:

• Are automating two 24V swing gate motors
• Do not require encoder-based positioning
• Want reliable safety via amperometric detection
• Prefer a simpler, cost-effective control solution
• Need a boxed control unit with integrated radio

You may want an alternative if you:

• Require encoder-based precision and synchronisation
• Are installing very large or uneven gate leaves
• Are working with 230V motor systems

ACS Team Insight

The CT20324 is a solid choice for standard residential swing gate installations where encoder feedback isn’t essential. By relying on amperometric safety, it keeps wiring and setup straightforward while still meeting safety requirements.

We often recommend it for medium-weight gates where smooth operation and reliability matter more than ultra-precise positioning.
