Each input can be configured as a low-current LED output, and the device supports a multi-tap function sending up to 4 values/DPTs, group control via long/extra-long press, pulse and switching counters, and 4 integrated logic modules. Contacts can be configured as NO or NC, and it has an integrated bus coupler for direct KNX connection, measuring 41 x 41 x 12 mm.
