32 Discrete Inputs with Channel Grouping

This module provides 32 discrete input points grouped into four distinct channels. The channel grouping enhances signal management and simplifies configuration, allowing users to optimize the module’s performance within their systems. With positive (sink) logic input, the 140-DDI-353-00 is well-suited for applications requiring robust noise immunity and reliability in data collection from multiple sources.

Voltage and Current Specifications

The 140-DDI-353-00 supports a discrete input voltage of 24 V DC, with input voltage limits ranging from 19.2 to 30 V DC. The module’s sensitivity is fine-tuned, guaranteeing a high state (state 1) detection at voltages between 15 and 30 V DC and a low state (state 0) detection between -3 and 5 V DC. This module also specifies a guaranteed state of one current at ≥ 2 mA when the supply voltage (Us) is 5.5 V, the input voltage (Uin) is 0 V, and a state 0 current of ≤ 0.5 mA. This configuration ensures that only accurate signals are processed, minimizing the risk of erroneous data collection due to minor voltage fluctuations.

Response Time and Frequency Compatibility

Engineered for applications demanding fast processing, the 140-DDI-353-00 boasts a response time of ≤ 1 ms when transitioning from state 1 to state 0 and vice versa. This rapid response capability supports real-time monitoring and control, making it ideal for dynamic environments where timely decision-making is crucial. The module’s fast response time also accommodates high-frequency switching operations, enhancing its versatility across various applications.

Protection and Isolation Features

Safety and resilience are at the core of the 140-DDI-353-00’s design, with built-in input protection via resistor-limited circuitry that safeguards against potential overvoltage conditions. The module’s isolation capabilities are extensive, offering 1780 Vrms isolation between group and bus for one minute and 500 Vrms isolation between groups for one minute. This high-level isolation minimizes interference and crosstalk, promoting stability and accuracy across the entire system, even in complex setups.

Power Dissipation and Signaling

The module’s power dissipation is carefully managed, with a base dissipation of 1.7 W and an additional 0.36 W for each active point. This efficient power usage model allows the 140-DDI-353-00 to operate optimally without overloading the system’s energy resources. For ease of monitoring, the module features local signaling with 32 green LEDs indicating input status, a red LED to signal external faults, and a green LED showing bus communication activity. These indicators enable quick visual diagnostics, simplifying system maintenance and troubleshooting.

Compliance and Bus Requirements

The 140-DDI-353-00, certified with the CE marking, complies with stringent European safety and quality standards, providing users with a trustworthy solution for industrial automation needs. The module requires a bus current of 330 mA, making it energy-efficient and compatible with various industrial control setups.
