KL3361 | Bus Terminal, 1-channel analog input, voltage, ±20 mV, 15 bit, oscilloscope function 

The KL3361 analog input terminal makes it possible to perform non-central preliminary processing of analog values. It is designed to measure a voltage in the mV range, such as occurs at a strain gauge full bridge. For operation of the full bridge, the KL3361 also has an internal 5 V supply. The input values are digitized with a 14 bit resolution and written into an internal memory. An efficient processor can pre-process the values. Limit values and maximum and minimum values can be determined or monitored. The KL3361 can also carry out envelope curve monitoring. A trigger starts the cyclical processes. The result or all the measured values are transported to the higher-level automation unit.
