Receiver 3.2.3.1. General Functionality In principle, the ZIOL2xxx IC family has two 9 identical input channels with a configurable feature set. The input threshold levels can be set ratiometric or absolute. The absolute values are compatible with definition of Type 1 digital inputs in IEC61131-2 and conform to the IO-Link specification. The ratiometric levels 10 are proportional to the HV power supply voltage. The ratiometric level configuration allows the input channels to function down to a 9 Note: The IC versions ZIOL22xx/21xx have only one receiver. 10 Note: Ripple on the supply voltage may have influence to the trip-point of the input stage. Another influence to be considered is that an enabled analog input filter is reducing the ripple on the on the received signal. |
