Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM3 Complete Model Number TM3DQ16UG Module Type Digital Output Module (Discrete Output) Number of Channels 16 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 16 channels combined, with derating) Peak Current per Channel 2 A for 100 ms (inrush) Voltage Drop (On-state) Typically < 0.8 V at 0.5 A Leakage Current (Off-state) < 0.1 mA Switching Frequency Up to 1 kHz (resistive load) Short-Circuit & Overload Protection Yes (electronic, per channel). Module signals a fault to the controller. Isolation 500 V AC between field side (outputs) and logic side (bus). No isolation between channels. Status Indicators • 1x Module Status LED (Bicolor): RUN/ERR (Green/Red) • 1x Power OK LED (Green): 24V supply presence • 16x Channel Status LEDs (Green): Indicates ON state of each output Connection Removable screw terminal block (front connector) 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 70 mA Load current: Sum of all active outputs (up to 4A max). Backplane Current (5V DC from bus) Typically 100 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 or Control Expert). Typical Applications Controlling actuators (valves, cylinders via solenoids), motor starters (contactors), warning lights, and other ON/OFF devices in machines and industrial control systems.
