Schneider Electric 140DDO35301

Schneider Electric 140-DDO-353-01 DC Discrete Output Module

The Schneider Electric 140-DDO-353-01 DC Discrete Output Module is a high-capacity output solution within Schneider's Modicon Quantum automation system. Designed for demanding applications, this module accommodates 32 discrete outputs organized into four groups of 8, each supporting positive logic (source) operations. This setup is ideal for applications that require multiple output channels, robust electrical isolation, and reliable monitoring in industrial automation environments. The module's standard format and a two-year MRO Electric and Supply warranty ensure quality, longevity, and optimal performance in various automated control systems.

Output Specifications and Configuration

The 140-DDO-353-01 module is engineered to handle a 24 V DC discrete output voltage, with a specified range between 19.2 and 30 V DC. This wide operating range makes it adaptable to various low-voltage applications. Each output channel is designed with positive logic (source) and requires two output words for addressing. The module's maximum absolute output can reach 50 V, although only for a brief decaying pulse of 1 second, making it a durable choice for applications where voltage fluctuations might occur momentarily.

Current and Load Management

This module has a robust load capacity. Each module is rated for a total maximum current of 16 A, distributed across four groups. Each group can handle up to 4 A, providing flexibility in current distribution and load management. The module also offers significant surge protection, with a surge current rating of up to 2 A. A voltage drop of 0.4 V at 0.5 A ensures efficient energy transfer, minimizing power loss during operation.

Response Time and Leakage Specifications

Designed for speed, the 140-DDO-353-01 provides rapid response times of less than or equal to 0.1 ms when switching from state 1 to 0 and less than or equal to 1 ms when switching from state 0 to 1. This high responsiveness is critical in environments where real-time control and quick responses are essential. Furthermore, the module maintains a leakage current of no more than one mA at 24 V, which ensures efficient power management and minimal unintended current flow in deactivated states.

Protective Features and Isolation

To ensure safety and reduce the risk of overcurrent damage, each point on the module is protected with a 3 A fuse, while each group is safeguarded with a 5 A fuse. The module also includes robust isolation features, with an isolation rating of 1780 Vrms DC between channels and the bus and 500 Vrms DC between groups for one minute. This high isolation level prevents interference between channels and enhances safety for operators and connected equipment. Additional protection is provided through internal output protection and fault indication for field power loss or blown fuses.

Power Requirements and Local Signaling

Operating efficiently with a bus current requirement of 330 mA, the module's power dissipation is capped at 5 W. This efficient energy profile makes it well-suited for energy-conscious installations while maintaining powerful functionality. Local signaling is facilitated through multiple LEDs: a green LED indicates active bus communication, a red LED alerts to external faults, and each of the 32 channels has a green LED to signify output status. The module carries a CE marking, certifying compliance with international standards and making it a reliable component for various global applications.

FAQs

What is the purpose of the isolation in the 140-DDO-353-01 module?

The module features isolation of 1780 Vrms DC between channels and the bus and 500 Vrms DC between groups. This isolation protects against electrical interference between channels, enhancing the module's safety and reliability in high-voltage or noisy environments.

How much current can each output point handle?

Each point on the module is rated for up to 3 A with a maximum current of 16 A for the entire module. This is distributed as 4 A per group of 8 output channels, providing flexibility for handling various loads.

What are the response times for the 140-DDO-353-01 module?

The module is designed for rapid switching, with a response time of less than or equal to 0.1 ms from state 1 to state 0 and less than or equal to 1 ms from state 0 to state 1. This quick response enables efficient control in high-speed applications.

What protective measures does the module include?

The 140-DDO-353-01 module includes:

• Transient voltage suppression.
• Internal 3 A fuses for each output point.
• 5 A fuses for each group.

It also provides fault indication for field power loss and blown fuses, which helps to quickly identify and resolve issues.

What is the acceptable range for the discrete output voltage?

The module is rated for a discrete output voltage of 24 V DC, with acceptable limits ranging from 19.2 to 30 V DC. It can handle a brief surge up to 50 V for 1 second, accommodating transient conditions without compromising performance.
