Dimming Actuators

The MDT Analog In / Output AIO is suitable for controlling devices with 0-10 V input (e.g. ventilation systems) and for recording 0-20 mA (4-20 mA) / 0-10 V measurement data (e.g. from fill-level or pressure sensors).

Each channel can be configured both as an input and as an output and is galvanically separated from the KNX bus.

• The KNX/DALI Gateway communicates with up to 64
• DALI actuators per channel. These can be connected and dimmed in up to 16 groups per channel.
• The gateway also supports selected sensors with DALI interface.
• It also records and transfers DALI status and error messages.
• An individual name, a group, parameter and scenes are assigned to individual DALI ECG´s during commissioning with the ETS (Engineering Tool Software).
• DALI sensors and their functionality are also assigned in the ETS.
• All DALI subscribers and functions are independent and can be linked via group addresses.
• The device can only be operated in DALI segments with connected ECGs and sensors and not with further DALI controllers within the segment (no multi-master mode).
• The power needed for ECGs and sensors is supplied directly through the gateway. An additional DALI power supply is not required, neither is it permitted.
