The 140DDM39000 mixed discrete I/O module belongs to Schneider Electric's Modicon Quantum automation platform. This compact unit combines 16 digital input points and 8 solid-state output points. All inputs and outputs operate at 24V DC with sink logic. The module organizes inputs into two groups of eight and outputs into two groups of four. Furthermore, it requires only one input word and half an output word for addressing. This I/O mix suits applications needing moderate I/O counts without occupying multiple slots.
The 140DDM39000 offers 16 discrete inputs with sink logic configuration. Input voltage is rated at 24V DC with limits of 30V continuous. The module tolerates 56V for 1.3 ms and 1V for 10 seconds during voltage dips. A guaranteed off-state voltage ranges from -3 to 5V, while the on-state starts at 15V and extends to 30V. Off-state current stays below 0.5 mA, and on-state current reaches at least 2 mA. Input impedance measures 2500 Ohms for consistent signal loading.
For outputs, the 140DDM39000 provides 8 solid-state sink outputs. Output voltage operates at 24V DC typical, with limits of 19.2 to 30V. Each point handles up to 0.5A load current, with 2A per group and 4A per module maximum. Voltage drop stays below 0.4V at full load. The module withstands 5A for 500 µs per point for brief overloads. Maximum load inductance reaches 500 mH at 4 Hz, and load capacitance extends to 50 µF. Output response time measures less than 1 ms for both on-to-off and off-to-on transitions.
The 140DDM39000 includes comprehensive protection features. Outputs have transient voltage suppression for overvoltage protection. Inputs are resistor-limited for current control. Internal output protection uses a 5A fuse per group. Isolation between groups reaches 500Vrms for one minute. Isolation between groups and the bus achieves 1780Vrms for the same duration. Fault indications include blown fuse detection and loss of field power on outputs. Local signalling includes green LEDs for bus communication and output status. Red LEDs indicate faults on inputs, outputs, and field power loss. This diagnostic coverage simplifies troubleshooting and maintenance.
Bus current requirement is 330 mA from the Quantum backplane. Power dissipation calculates as 1.75W plus (0.36 x input points on) plus (1.1 x total output load current). This efficient design minimizes heat within the rack. The module weighs 0.3 kg (0.7 lbs) net. Package dimensions are 16.3 cm height, 4.5 cm width, and 31.2 cm length. Operating temperature ranges from 0 to 60°C (32 to 140°F). Storage temperature spans -40 to 85°C (-40 to 185°F). Relative humidity tolerance reaches 95% without condensation. Operating altitude extends to 5000 meters. The module meets ESD immunity per IEC 801-2 at 4kV contact and 8kV air. Electromagnetic field immunity complies with IEC 801-3 at 10V/m.
First, power down the Quantum rack before inserting the 140DDM39000. Slide the module into the chosen slot until it seats properly. Next, connect field wiring to the front connector following the terminal assignments. Wire input devices to the designated input terminals with proper polarity. Connect output loads to the output terminals, ensuring current stays within per-point and per-group limits. Use appropriate wire gauges for the expected currents. After wiring, apply power and verify the green Active LED illuminates. Check the red LEDs for any fault indications. Finally, configure the I/O mapping within the Unity Pro or Concept software environment.

1. Q: Are the inputs and outputs isolated from each other?
A: Yes, the 140DDM39000 provides isolation between input and output groups. This isolation reaches 500Vrms between groups and 1780Vrms from the bus.
2. Q: Can I mix input and output wiring in the same cable?
A: We recommend separating input and output wiring to reduce noise coupling. The module's group isolation supports this separation effectively.
3. Q: What happens if an output fuse blows?
A: The module indicates a blown fuse with a red LED. You must replace the module to restore that output group. The fuse is internal and not field-replaceable.
4. Q: Does this module support sourcing outputs?
A: No, the 140DDM39000 provides sinking outputs only. This configuration connects the load between the positive supply and the output terminal.
5. Q: How do I calculate the total power dissipation for my system?
A: Use the formula: 1.75W + (0.36 x number of active inputs) + (1.1 x total output current in Amps). This calculation helps estimate heat load in the rack.
