4-Channel 20A Switch Actuator Module with Current Detection
19 Sep, 2025
In today’s smart building and commercial lighting projects, one of the biggest challenges is how to manage high-power loads reliably and cost-effectively. Traditional solutions such as KNX-based switch actuators are powerful, but they come at a high cost that makes large-scale deployment difficult. At the same time, building owners demand greater stability, energy efficiency, and flexibility in their lighting control systems.
EASYCTRL, a professional source manufacturer of smart lighting control modules, has developed the 4-Channel 20A Switch Actuator Module with Current Detection based on the YC-BUS protocol. This innovation delivers the same stability and performance you would expect from high-end international standards, but at only one-third of the cost of KNX modules.
Our 4-Channel 20A actuator with current detection is purpose-built for projects that require heavy-duty switching capacity, such as charging stations, museums, hotels, shopping malls, and public facilities.
Key Features:
Standard 35mm DIN rail installation: Occupies 4P module units.
Equipped with Fanhua single contact magnetic latching relay, providing 4-channel 20 A relay switching.
Each circuit can independently control devices up to 4400W.
Supports setting the initial power-on state for each circuit (on, off, or previous power state).
Manual Override (Force Switch）
Guarantees safety and usability during system maintenance or network downtime.
YC-BUS Protocol
Proprietary communication technology developed by EASYCTRL — stable, flexible, and cost-effective
Compact DIN-Rail Installation
Standard 4P width, designed for easy integration into distribution cabinets.
