Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM3 Complete Model Number TM3DQ16R Module Type Digital Relay Output Module Number of Channels 16 Contact Type per Channel Form C (SPDT - Single Pole Double Throw) / Changeover (1 NO + 1 NC) Contact Material Silver alloy Maximum Switching Voltage 250V AC / 30V DC Maximum Switching Current 2 A per contact (resistive load @ 30V DC or 250V AC) Inrush Current Capacity • Lamp Load: 30W @ 250V AC • Inductive Load (@ cosΦ=0.4): 0.2 A @ 250V AC Minimum Switching Load 10 mA at 5V DC (for reliable contact operation) Electrical Endurance • At rated load (2A): Typically 100,000 operations • At minimum load: Typically 10,000,000 operations Mechanical Endurance Typically 20,000,000 operations Switching Frequency Up to 2 Hz (for maximum contact life under load) Operate/Release Time Typically < 10 ms Isolation • Between coil and contacts: 1500V AC • Between contacts of different channels: 500V AC • Between contacts and backplane/bus: 500V AC Status Indicators • 1x Module Status LED (Bicolor): RUN/ERR (Green/Red) • 16x Channel Status LEDs (Green): Indicates when the relay coil is energized (ON state). 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 Supply (for relay coils) 24V DC (supplied via the TM3 base unit). Crucial: The module consumes power to energize all 16 relay coils. Coil Power Consumption • Per-channel coil current @ 24V DC: Typically 15-20 mA. • Total module coil current (all 16 ON): Can reach ~320 mA. This must be factored into the 24V power supply sizing for the entire system. Backplane Current (5V DC from bus) Typically 100 mA (for module logic, 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) 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 AC solenoids, contactor coils, indicator lamps, small motors (via contactors), and any load requiring voltage isolation or switching different voltage types from the PLC's logic
