Specifications Parameter Category Details Manufacturer & Series Schneider Electric, Modicon TM3 Complete Model Number TM3RDM16R Module Type Digital Relay Output Module Number of Channels 16 Contact Type per Channel Form C (SPDT - Single Pole Double Throw) / Changeover (1 Normally Open + 1 Normally Closed) Contact Material Silver alloy Rated Load Voltage (Max) • 250V AC • 30V DC Maximum Switching Current • 2 A per contact (resistive load @ 30V DC or 250V AC) Maximum Inrush Current • 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 wetting) Electrical Endurance • At rated load: 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 electrical life) 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 or external terminal). The module consumes power to energize the relay coils. Coil Power Consumption Logic current from 5V bus: ~100 mA. Per-channel coil current @ 24V DC: Typically ~15-20 mA. Total module coil current can be significant (e.g., up to ~320 mA for all 16 channels ON). This must be considered for power supply sizing.
