Schneider Electric MTN649912 KNX Blind / Switch Actuator REG-K 12x/24x/10

The Schneider Electric MTN649912 is a KNX blind/switch actuator that lets you operate up to 12 blind or roller shutter drives or up to 24 switching loads using make contacts. It has a built-in manual mode, can be mounted on a DIN rail, and has strong 10 A outputs, making it a good choice for professional KNX smart home and commercial building projects.

Details of Schneider Electric MTN649912 KNX Blind / Switch Actuator

You can set up each of the 12 blind channels to work with either a blind or roller shutter, or you can split them into two switching channels. This lets you manage up to 24 loads using create contacts for maximum flexibility during commissioning.

The MTN649912 is perfect for applications where you need to shield against the sun and turn things on and off with a single little device on the DIN rail. ​

The actuator is made to be mounted directly on ordinary DIN rails. It has a built-in KNX bus coupler and clear status LEDs for each channel to make installation, troubleshooting, and maintenance easier on distribution boards.

The manual control buttons on the front let you operate every blind and switching output from the front. This is very helpful when the KNX line is down for maintenance or commissioning work.

The device may work in a number of different ways, getting power from both the bus and the mains voltage, or only the bus. This makes it very reliable in tough building automation settings. ​

The MTN649912 can do all the normal KNX tasks, like controlling scenes, sending central orders, reacting to weather alarms, and flexible time functions like on/off delays and staircase lighting logic to set up complex automation scenarios.

ETS software allows for fine-tuning of blind running times, slat angle control, reference runs, and behavior after a bus or mains failure to protect motors and make sure that the installation stays in the right position for its entire life. Each output can handle 10 A at 230 V AC, which is good for inductive loads like blind motors. It has the right switching frequency and upstream protection to make sure it works reliably. ​

Key Features and Benefits

• 12 blind channels or up to 24 switching outputs for easy KNX management of loads, shutters, and blinds.
• Integrated manual mode with keys on the front panel and status LEDs for easy testing, commissioning, and service.
• DIN-rail REG-K design with a built-in KNX bus coupler that makes it easy to connect to distribution boards and KNX lines.
• 10 A rated outputs at 230 V AC that work with blind motors and other loads. Each channel should have a 10 A protection upstream.
• Advanced KNX features like scenes, central commands, weather alarms, logic, and time functions to help with complicated building automation ideas.
