Primary Contents


Why does the H5CR, H8CA-S, H5CX (except the H5CX-A11/-A11S), and H3CA not operate even when an input is sent?


The AC power supply may have taken unwanted current paths, causing damage to the internal parts.


The H5CR uses a transformerless power supply.

Do not simultaneously input two or more power supplies from a single input contact or transistor to separate Timers (or Counters).
