Schneider Electric 140DDI84100

The Schneider Electric Part Number 140DDI84100 is a DC Discrete Input Module designed for industrial automation applications. As an I/O (Input/Output) module, it serves as a crucial interface between field devices and a control system, allowing the monitoring of external digital signals. This module is part of Schneider Electric's product line and comes with a 2-year warranty, ensuring reliability and performance.

Function

The 140DDI84100 module format follows the standard format for ease of integration into various industrial setups. It offers 16 discrete input channels, grouped into 8 channels. The logic input for these channels is positive (sink), meaning it detects a signal when the input voltage is brought to a low level (0 V).

The input voltage limits for this module range from 10 to 60 V. Depending on the input voltage range, the module supports different input current levels. For example, for a 60 V input, the supported current is 1 to 5 mA DC, while for a 48 V input, the supported current is 2 to 15 mA DC.

The module guarantees specific voltage states for accurate signal detection. For voltage state 1, the module guarantees a voltage range that varies depending on the input voltage, ranging from 9 to 12 V for a 60 V input to 12 V ± 5% for a 12 V input. For voltage state 0, the guaranteed voltage range is 0 to 9 V for a 60 V input to 0 to 1.8 V for a 12 V input.

It's crucial to observe the absolute maximum voltage, which is 75 V. Operating beyond this limit can damage the module and connected devices.

Communication

Addressing the module requires 1 input word, which means it occupies one data word in the control system's memory. The response time for switching between voltage states is 4 ms, both from state 1 to state 0 and vice versa. The switching frequency for the module is limited to a maximum of 100 Hz, ensuring stable and reliable operation.

The module provides isolation between the group and the bus, which is essential for safety and noise reduction. The isolation level between the group and the bus is 2500 Vrms DC for 1 minute, and between the individual group members, it is 700 Vrms DC for 1 minute.

Features

The power dissipation of the 140DDI84100 module is 1 W plus an additional 0.62 W for each point connected to it. The power dissipation indicates the amount of heat generated during operation.

The module features local signaling through LEDs. There are 16 green LEDs to indicate the input status, 1 red LED to indicate external fault detection (F), and 1 green LED to show that bus communication is active.

Operation

For proper operation, the module requires a bus current of 200 mA.

The 140DDI84100 module is marked with the CE mark, indicating its compliance with relevant European Union regulations and standards for safety and electromagnetic compatibility.

Overall, the Schneider Electric 140DDI84100 DC Discrete Input Module is a reliable and versatile device that facilitates the integration of external digital signals into industrial control systems. Its high-quality design, protection features, and local signaling capabilities make it suitable for various automation applications, enhancing the efficiency and reliability of industrial processes.
