140DAI55300 (Part Number: 140DAI55300) is a 32-channel AC discrete input module for the Modicon Quantum platform. It interfaces with 115 V AC signals, enabling monitoring of field devices such as limit switches, pushbuttons, and relay contacts.
The module organizes channels into four independent groups of eight, allowing multiple AC phases or sources while maintaining robust isolation and front-panel LED diagnostics for rapid troubleshooting.
