ABB JA/M2.24.1 is the ABB i-bus® KNX Shutter Actuator Module, 2-fold, 24 V DC. Its relay contacts switch two independent low-voltage electric drives such as shutter motors or ventilation-flap drives.

It snaps into a compatible RC/A4.2 or RC/A8.2 Room Controller slot. The host supplies the module interface, detects the inserted type and provides KNX communication, ETS parameterisation and manual functional testing. The module is not a standalone KNX device.

Function and Application

• Channels: 2 mechanically interlocked reversing outputs.
• Application: Reversing control of two independent 12/24 V DC drives.
• Host compatibility: RC/A4.2 and RC/A8.2 basis devices.
• Commissioning: Through the selected host Room Controller application; there is no separate module KNX address or product database.

Installation and Safety

Connect only compatible DC drives, observe supply polarity and never use the interlocked relay outputs as a safety isolator. Isolate the Room Controller and all field/load circuits before inserting, removing or wiring the module. ABB currently publishes IP54 for the product; treat this as a configured Room Controller value, not a freestanding enclosure rating.

Use the model-specific technical data, instructions, diagrams and declarations below. Shared manuals may retain historical host names, while ABB's current compatibility records explicitly associate this module with RC/A4.2 and RC/A8.2.
