Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM3 Complete Model Number TM3DQ32TK Module Type Digital Output Module (Discrete Output) Number of Channels 32 Output Type Sourcing (PNP) – Switches the positive (24V) side of the load. Common negative. Rated Load Voltage 24V DC (for output power) Supply Voltage (for module logic) 24V DC (via the TM3 bus or external terminal) Nominal Output Current per Channel 0.5 A Maximum Total Current per Module 4 A (for all 32 channels combined, with significant derating to prevent overheating). Peak Current per Channel 2 A for 100 ms (inrush) Voltage Drop (On-state) Typically < 1.0 V at 0.5 A Leakage Current (Off-state) < 0.1 mA Switching Frequency Up to 1 kHz (resistive load) Short-Circuit & Overload Protection Group Protection (likely in banks of channels, e.g., 8 or 16 channels per group). Module signals a fault to the controller. Isolation 500 V AC between field side (outputs) and logic side (bus). No isolation between individual channels within a group. Status Indicators • 1x Module Status LED (Bicolor): RUN/ERR (Green/Red) • 1x Power OK LED (Green): 24V supply presence • Banks of Channel Status LEDs (Green): Indicates ON state for groups of channels (e.g., one LED per 8 or 16 outputs, not per individual channel due to high density). Connection High-density, removable screw terminal block (front connector) with compact pitch for field wiring. Wire Gauge (Terminal) Solid or stranded: 0.5 mm² to 1.5 mm² (AWG 20 to AWG 16) Power Consumption from 24V DC Logic current: Typically 100 mA Load current: Sum of all active outputs (up to 4A max for the entire module). Crucially, not all 32 channels can be used at full 0.5A simultaneously. Backplane Current (5V DC from bus) Typically 150 mA (supplied via the TM3 base unit) Operating Temperature 0°C to +55°C Storage Temperature -25°C to +70°C Relative Humidity 5% to 95% (non-condensing) Pollution Degree 2 Protection Rating IP20 (for installation inside an enclosure) Mounting DIN rail (35mm) mounting via a compatible TM3 base unit (e.g., TM3XB) Compatible Controllers Modicon M221, M241, M251, TM2, and other PLCs supporting the TM3 I/O system. Configuration Automatically detected and configured by the controller's programming software (EcoStruxure Machine Expert). Typical Applications Controlling large arrays of actuators in packaging machines, material handling systems, assembly lines, and lighting control where a high number of ON/OFF signals are required from a compact module.
