Power for the Triac outputs must be reduced if the max. load of 18 VA is required for AC 24 V field supply on the DXR2.x18.

NOTE: To calculate the total VA, add the Base Load + number of Triacs + field supplies+ KNX PL-Link. This cannot exceed the maximum power consumption. See Wiring Guidelines for Field Panels and Equipment Controllers (125-3002) for more information.
