The supply voltage Uv can be
drawn from the terminal or
can be supplied from an
external source. The terminal
supplies 5 V. The maximum
input voltage U is limited
to 10 V.

KL3361 | 1-channel oscilloscope terminal -20…+20 mV

The KL3361 analog input terminal makes it possible to perform non-central preliminary processing of analog values. The input values are digitised 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.
