Schneider Electric 140DDO84300 Overview

Schneider Electric 140DDO84300

The Schneider Electric Part Number 140DDO84300 is a high-quality DC discrete output module designed for industrial automation applications. Manufactured by Schneider Electric, a trusted name in the industry, this module delivers reliable performance and robust functionality. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.


The 140DDO84300 module falls under the category of I/O Modules and is a standard format module. It is specifically designed as a DC discrete output module, providing 16 discrete output channels for controlling external devices or processes. These outputs are divided into two groups, each consisting of eight channels.


The module operates on negative logic, also known as sink logic, which means that the output is active when the logic signal is low. It requires 1 output word for addressing, making it easy to integrate into a control system or network.


The discrete output voltage range of the module is 10 to 60 V DC, with output voltage limits of 10.2 to 72 V. The module can withstand a maximum permanent output voltage of 72 V, ensuring durability and protection against voltage spikes. It exhibits a voltage drop of less than or equal to 1 V at 2 A load current.

Each module can handle a maximum load current of 12 A, while the load current per group is limited to 6 A. In the event of a surge, the module can handle surge currents of up to 7.5 A for 50 seconds. The response time of the module is impressively fast, with transition times of less than or equal to 1 ms between state 0 and state 1, as well as between state 1 and state 0.


The module features internal output protection through an 8 A fuse per group, ensuring the safety of the connected devices. The associated fuse rating for each discrete output point is 2 A, while each group requires an 8 A fuse.


Safety and isolation are essential in industrial applications, and this module provides adequate protection. It offers isolation between channels and the bus at 2500 Vrms DC for 1 minute, and isolation between the two groups at 700 Vrms DC for 1 minute. These isolation measures contribute to enhanced safety and prevent interference between channels and groups.


The module is marked with the CE certification, indicating its compliance with European safety standards. It also features local signaling through LEDs, including a green LED indicating bus communication activity, a red LED indicating external fault detection, and 16 green LEDs displaying the input status.

In terms of power requirements, the module consumes 160 mA of bus current. The power dissipation is calculated as 1 W plus 1 V multiplied by the total module load current, ensuring efficient power management.

Backed by a 2-year warranty, the Schneider Electric 140DDO84300 module offers reliable performance, flexibility, and safety for various industrial automation applications. Its robust construction, high-speed response time, and comprehensive protection features make it an excellent choice for controlling discrete outputs in industrial settings.
