10.2 Notes for selection of replacement for Triac output module AY22
Although QY22 can be selected as a replacement module for AY22, the modules partially differ in
specifications, and the maximum load current of QY22 is lower. Therefore, it is necessary to confirm
whether the existing connected devices meet the maximum load current specification.
