Product Overview
The Schneider TM3DQ8T is an 8-channel discrete output expansion module from the Modicon TM3 series, designed to extend the digital output capacity of Modicon M221, M241, M251, and M262 logic controllers. It features 24 VDC transistor outputs with source (PNP) logic, enabling direct control of actuators such as relays, lamps, solenoids, and other devices in automation systems.
Its compact design, fast switching frequency, and DIN-rail mounting make it ideal for machine-level automation. Moreover, built-in short-circuit and overload protection ensures reliable operation, making it a cost-effective solution for industrial control systems.
