Schneider Electric TM3DQ32TK Digital Output Module

Schneider Electric TM3DQ32TK is a 32-channel digital output expansion module for the Modicon TM3 family, designed to be mounted on the TM3 backplane to extend the processor's I/O capability without expanding the main chassis. It delivers 32 regular transistor outputs (source/PNP) configured to switch 24 V DC signals, with each output limited to 0.1 A and a shared current capability of up to 2 A per common line, enabling reliable control of a bank of low-current actuators under centralized PLC supervision. The 32 outputs are accessed through HE10 (MIL 20) connectors, which align with Schneider Electric's TM3 I/O hardware interface and support compact, dense wiring in rack-based automation setups. This expansion module is intended for use in industrial automation applications where a TM3 CPU requires additional remote I/O to drive 24 V loads such as relays, contactors, lamps, or indicator devices, while keeping the control logic on the TM3 controller. Typical catalog listings note an IP20 protection rating for the module, reflecting its suitability for standard indoor industrial environments.
