SIN/COS SIGNAL SAFETY MONITOR IC
Rev C2, Page 10/14
The following ï¬gure shows a SIN signal (PSIN-NSIN) and a COS signal (PCOS-NCOS) leading by just 45°, as
well as the Lissajous ï¬gure resulting from this phase shift. Additionally, the result of square sum generation is
also shown, here exceeding the monitoring thresholds for the maximum and minimum amplitudes.

Input Circuits With Operational Ampliï¬ers
For the detection of signal losses, caused by a fractured cable for instance, iC-RC1000 drags its input signals
into the DC checkâs error range using integrated pull-down resistors. If operational ampliï¬ers are connected
upstream, cable fracture detection now requires that the external circuit ensures an open external input causes
an invalid input signal at iC-RC1000 (violation of DC commen mode range).
