The Mitsubishi Q Series output modules, specifically the QY71 and QY81P, are engineered to deliver exceptional performance in demanding industrial automation environments. The QY71 is a 32-point sink-type transistor output module operating at 5-12 V DC, ideal for low-voltage logic control, while the QY81P offers 32-point source-type transistor output at 12-24 V DC, suitable for higher voltage actuator and relay driving. Both modules provide high-speed switching, minimal power consumption, and robust noise immunity, ensuring reliable operation in PLC-based systems. They are fully compatible with the Mitsubishi Q Series backplane and support easy configuration via GX Works software.
