The QX28AC Input Module is an 8-point digital input module accepting 240VAC on each channel, intended for sensing discrete AC signals in a control system.
Rated input voltage of 240VAC means each of the 8 points is designed to reliably detect a nominal 240 VAC line signal — common for direct sensing of motor contactor auxiliaries, valve limit switches, or pilot lights in AC control circuits without an interposing relay. With 8 input points, this module fits applications where a moderate number of AC-level digital signals need to be brought into the controller — enough for a small motor control center section or a burner management input group, provided the scan rate and isolation meet the system's requirements.
For a BOM line requiring this exact module, the sourcing posture is quoted-to-order against an RFQ — typical lead time falls in the 1–10 working day window, but the buyer should confirm availability at time of order.
