ABB SD/M2.6.2 is the ABB i-bus® KNX Switch/Dim Actuator Module, 2-fold, 6 AX. It switches and dims two groups of luminaires with electronic ballasts through a 1…10 V control interface and enhanced switching capacity. It replaces SD/M2.6.1.

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 independently switched and dimmed lighting groups.
• Application: Two-channel switching and 1…10 V dimming of electronic-ballast lighting groups.
• 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.
