PLCs, Power Supplies & Others

The Schneider 140DAI54000C discrete input module captures digital signals from field sensors. This unit weighs 0.35 kg and measures 14.0 cm x 6.5 cm x 5.0 cm. It provides 32 discrete input channels for the Modicon Quantum system. The module contains 32 opto-isolators and one logic interface IC. For energy storage, it includes one 100µF electrolytic capacitor. Consequently, the Schneider 140DAI54000C maintains input states during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the Schneider 140DAI54000C. Use this data for your system integration planning.

Input Channel Features

Each of the 32 input channels uses a dedicated opto-isolator for signal isolation. The Schneider 140DAI54000C accepts 24V DC signals from standard industrial sensors. Therefore, you can connect proximity switches, limit switches, and push buttons directly. The input current sits at 6 mA for reliable detection. Thus, the module presents a light load to your field devices.

Switching Performance

The response time reaches 1.5 milliseconds for both on-to-off and off-to-on transitions. Consequently, this input module captures fast digital events accurately. The on-state voltage range spans 15V to 30V DC. The off-state voltage stays below 5V DC for guaranteed detection. Hence, the Schneider 140DAI54000C provides clear and noise-immune signal recognition.

Power and Energy Storage

The Schneider 140DAI54000C draws 120 mA from the 5V DC backplane bus. Hence, its total power consumption equals 0.6W. The onboard 100µF capacitor provides 8 milliseconds of hold-up time. This short backup protects input states during minor voltage sags. Furthermore, the module generates very little heat during operation.

Installation and Connectivity

You can mount the Schneider 140DAI54000C into any Modicon Quantum I/O slot. The module occupies one slot in the backplane chassis. The 40-pin connector handles all 32 input wirings via a pre-assembled cable. For best performance, use shielded cables for long input runs. The Schneider 140DAI54000C works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This discrete input module operates reliably from 0°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the Schneider 140DAI54000C suits most industrial control cabinets perfectly.
