Comparison with sibling models
Compared to the H7CX-A4 AC100-240, which uses a relay output, the H7CX-A4S-N AC100-240 switches via solid-state output — no contact wear for high-cycle applications. The H7CX-A11S-N AC100-240 offers a 6-character display and octal plug-in terminals instead of the 4-character screw-terminal layout here; pick that variant when a larger display or quick-disconnect wiring is required.
