Product Description
The KNX controller SK08-AN2 is part of the S8 device series and serves to measure two analog voltage values between 0 and 12VDC.
The sensor / controller has two ports, each with a ground, a signal input and a supply voltage pin ( e.g. for a sensor ).
The device has an integrated KNX bus coupler and required, depending on the measurement electronics and configure, an additional voltage between 9 and 30 volts.
The transducer is located in a high-strength, extremely robust stable impact ABS plastic housing. Cover and base have a revolving groove and tongue system with neoprene gasket. The housing is IP54/65.
In the application software there are several controllers available ( two-position or PI controller with continuous or pulsed output ) separately for both channels.
Additional functions include the display of upper and lower thresholds and switching between the set point and threshold.
The sensor is configured by ETS ( Tool Software ) and the application program. Controlling functions such as signal threshold and other adjustments are parameterized by the ETS.
Applications
- Measurement of two analog voltage values between 0 and 10VDC ( e.g. pressure sensors )
- Surveillance and control of chemical and physical measurements, sensor technology with voltage output.
