Modicon Quantum 140DDO84300C DC Output Module

Schneider 140DDO84300C DC Discrete Output Module

Product Introduction

The 140DDO84300C from Schneider Electric belongs to the Modicon Quantum automation platform. This module delivers 16 discrete outputs arranged in two groups of eight channels each. Each output follows positive logic sourcing.

You need only one output word for addressing. This keeps your PLC configuration simple and efficient. Additionally, the output voltage range spans from 10 to 60 volts DC. The absolute maximum permanent output reaches 72 volts DC.

Manufacturers use this module to drive solenoids, relays, and indicator lamps. For instance, it works well in material handling and packaging machines. Therefore, the 140DDO84300C provides flexible control for medium power loads.

Technical Specifications

The 140DDO84300C offers two isolated channel groups. Each group has independent return paths. Isolation between groups is 700 Vrms DC for one minute. Meanwhile, isolation between channels and the bus reaches 2500 Vrms DC.

Output voltage limits extend from 10.2 to 72 volts DC. Maximum voltage drop is less than 1 volt at 2 amps. Leakage current stays below 1 milliampere at 60 volts. This low leakage prevents false triggering of sensitive loads.

Response times are fast and consistent. State 0 to 1 takes less than or equal to 1 millisecond. State 1 to 0 also takes less than or equal to 1 millisecond. Consequently, the module supports high speed switching applications.

Maximum load current per module is 12 amps. Each group handles up to 6 amps. Surge current withstand capability is 7.5 amps for 50 microseconds. Furthermore, each point should use a 2 amp external fuse for additional protection.

Internal protection includes an 8 amp fuse per group. This fuse safeguards against overcurrent events. Power dissipation is calculated as 1 watt plus 1 volt multiplied by the total module load current. Therefore, efficient thermal management is easy to achieve.

Local Signaling and Diagnostics

The front panel provides clear visual feedback. Seventeen green LEDs indicate status. Sixteen green LEDs show individual output states. One additional green LED confirms active bus communication.

One red LED alerts you to external faults. A blown group fuse triggers this red LED. Loss of field power also activates the fault indicator. Thus, troubleshooting becomes quick and intuitive.

Environmental and Mechanical Data

The module operates between 0 and 60 degrees Celsius ambient temperature. Storage temperature ranges from -40 to 85 degrees Celsius. Relative humidity tolerates 95 percent without condensation. Additionally, operating altitude reaches up to 5000 meters.

Protective treatment uses conformal coating Humiseal 1A33. This coating resists moisture, dust, and mild chemicals. Moreover, certifications include UL 508, CSA C22.2 No 142, FM Class 1 Division 2, and GOST. These ensure compliance with global safety standards.

EMC resistance is robust. Electrostatic discharge withstands 4 kV contact and 8 kV air. Electromagnetic field resistance reaches 10 V/m from 80 to 2000 MHz. Thus, the 140DDO84300C performs reliably in electrically noisy environments.

Net weight is only 0.45 kg. Dimensions are 16.3 cm height, 4.5 cm width, and 31.2 cm length. This compact form factor saves valuable cabinet space.

Frequently Asked Questions

1. Can the 140DDO84300C switch 120V AC loads?
   No. This module provides only DC outputs from 10 to 60 volts. For AC loads, select an AC output module or use an interposing relay.

2. What happens when one group fuse blows?
   Only that specific group of eight outputs stops working. The other group continues normal operation. The red fault LED illuminates to alert you.

3. Do I need external fuses for each output point?
   External 2 amp fuses per point are strongly recommended. They protect wiring and loads before the internal 8 amp group fuse responds.

4. Can I use this module with 12V DC automotive systems?
   Yes. The 140DDO84300C operates from 10 to 60 volts DC. It works perfectly with 12V and 24V DC systems commonly found in vehicles.

5. How do I calculate the power dissipation for my configuration?
   Use this formula: 1 watt plus 1 volt multiplied by total load current. For example, if total load current is 2 amps, dissipation equals 1 plus 2 equals 3 watts.
