Schneider Electric 140DDI84100

Schneider Electric 140-DDI-841-00 DC Discrete Input Module

The Schneider Electric 140-DDI-841-00 is a high-quality DC discrete input module crafted to support industrial applications with precision and dependability. As a standard module format designed for automation and control systems, this model brings versatility and consistent performance to any industrial setup. The 140-DDI-841-00 is backed by a 2-year warranty from MRO Electric and Supply, offering users additional peace of mind with long-term reliability in mind. Its design focuses on handling multiple discrete inputs, making it an ideal choice for diverse control applications requiring a positive (sink) logic configuration.

16 Discrete Inputs and Channel Grouping

This module provides 16 discrete inputs organized into eight channel groups, streamlining signal management and enhancing the flexibility of its application. The channel group structure is beneficial for efficient input organization, which helps optimize system performance and supports complex configurations. With positive (sink) logic, the module is particularly suited for applications where high reliability and low noise susceptibility are essential.

Voltage Specifications and Input Sensitivity

Designed to accommodate a wide range of voltage levels, the 140-DDI-841-00 has input voltage limits of 10 to 60 V DC, allowing it to operate seamlessly with different input signals. The module supports specific current ranges for each voltage level: 60 V inputs require 1–5 mA, 48 V inputs require 2–15 mA, 24 V inputs require 6–30 mA, and 12 V inputs need 5–10 mA. For state detection, it guarantees a high (state 1) voltage between 9 and 12 V at 12 V, 45 to 60 V at 60 V, 34 to 48 V at 48 V, and 11 to 24 V at 24 V. For a low (state 0) voltage, it guarantees 0 to 9 V at 60 V, 0 to 5 V at 24 V, 0 to 10 V at 48 V, and 0 to 1.8 V at 12 V. The module’s maximum input voltage is capped at 75 V, protecting the unit from overvoltage risks.

Fast Response Time and Frequency Specifications

With a response time of 4 ms for changes between states (from state 1 to state 0 and vice versa), the 140-DDI-841-00 can accurately handle high-speed operations. This rapid response rate makes it highly suitable for applications that require quick input processing. Additionally, the module supports a switching frequency of up to 100 Hz, further contributing to its efficacy in dynamic control environments where real-time monitoring is essential.

Isolation and Power Dissipation

The module has high-level isolation features, providing 2500 Vrms DC isolation between each group and the bus for one minute and 700 Vrms DC isolation between groups, ensuring that interference and crosstalk are minimized. Power dissipation is 1 W, with an added 0.62 W for each active input point, allowing the module to maintain efficiency by adapting power usage based on the number of active inputs. This tailored approach to power dissipation is crucial for sustaining stable performance under varied load conditions.

Diagnostic LEDs and Compliance

The module includes 16 green LEDs to monitor the status of each input, a red LED to signal external faults, and a green LED to confirm active bus communication. This clear, visual feedback simplifies monitoring and troubleshooting, making it easier to identify and address issues. Marked with CE compliance, the 140-DDI-841-00 adheres to stringent European safety and quality standards, ensuring it meets regulatory requirements for industrial equipment.
