KNX Analog I/O 4-channel, 2 SU MDRC, 0 – 10 V, switchable In-/Output. Suitable as an analogue output to control ventilation systems and other devices with a 0-10 V input. Equally suitable as an analogue input to log RPM or other 0-10 V measured data. Each channel can be independently configured (in-/output). In-/output galvanically isolated from the KNX Bus. In-/output have a common GND. Voltage for output operation is generated in the actuator. No external power supply required. Input mode: Sensor type 0-10 V / 2-10 V or 0-20 mA / 2-20 mA (selectable), measured value scaling, adjustable data point types, min/max values, wire break detection, threshold value- and step control function. Output mode: 0-10 V, selectable data point type, control input via 1 bit / 1 byte / 2 bytes, lock function, emergency mode, Day/Night function to limit the control value. Fast application download (long frame support as of ETS 5). 3 year warranty.
