MDT Analog Input/Output – Precise control and measurement data acquisition
The MDT Analog Input/Output is a versatile KNX component for the precise control and acquisition of analog signals. Available as a 2-gang flush-mount device (AIO-0210V.01) or a 4-gang DIN rail device (AIO-0410V.01) , it enables the efficient implementation of 0–10V and 0–20mA applications in building automation. Ideal for lighting, climate, or energy management systems, the device combines high accuracy with easy integration into existing KNX infrastructures.
Key features
-
Independent configuration: Each channel can be individually parameterized as an input or output.
-
Galvanic isolation: All inputs and outputs are galvanically isolated from each other and from the bus to ensure maximum operational safety.
-
Input functions:
- Voltage range: 0–10V or 2–10V .
- Current loop: 0–20mA or 4–20mA .
- Features: Min/Max memory, wire break detection, threshold monitoring and traffic light function.
-
Output functions:
- Output voltage: 0–10V , controllable via 1-byte, 2-byte float or 1-bit objects.
-
Day/night operation for automatic setpoint limitation.
-
Emergency operation in case of setpoint failure for increased operational reliability.
-
Integrated power supply: No external power supply is necessary – the voltage for output operation is generated internally in the actuator.
