Description
iC-RC1000 acts as an independent monitoring device for industrial safety controllers and drive systems in the evaluation of sine encoders for SIL applications. In this function the IC checks that four analog signal lines have the correct DC voltage range (DC range: 30 to 80 % from VCC1 or VCC2) and that two respective paired lines have the correct differential 1 Vpp signal amplitude in real time (amplitude range: 200 to 300 mV). Single-ended signals referenced to ground with twice this amplitude (400 to 600 mV) can also be monitored; here, the negative input must be kept within the permissible DC range (e.g. VCC/2).
