Schneider 140DAI34000C 16-Channel Input Module

140DAI34000C Modicon Quantum Discrete Input Module

Product Introduction

The 140DAI34000C from Schneider Electric functions as a dedicated discrete input module within the Modicon Quantum PLC family. This module captures digital signals from switches, sensors, and other field devices, converting them into usable data for the central processor. Its 16 input channels and 24 V AC operating voltage make it a practical choice for many industrial monitoring and control applications.

Key Technical Specifications

The Schneider Electric 140DAI34000C provides 16 discrete input channels that operate at a nominal voltage of 24 V AC. This configuration allows it to interface directly with a wide range of standard industrial sensors and switching devices. For addressing purposes, the module requires 1 input word in the system's memory map.

In terms of electrical characteristics, the input current ranges from 10.7 to 12 mA, which ensures consistent and reliable signal detection. The module's maximum leakage current is specified at 1.9 mA, a critical parameter for minimizing false triggers and maintaining signal integrity. Additionally, it draws a bus current of 180 mA from the rack backplane and has a maximum power dissipation of 5.5 W, reflecting its efficient energy design.

Standards and Compliance

This input module carries the CE marking, confirming its conformity with essential European health, safety, and environmental protection standards. Moreover, it adheres to UL 508 and CSA standards, which are widely recognized benchmarks for industrial control equipment. These certifications provide assurance of the module's quality and its suitability for use in regulated environments.

Mechanical and Environmental Parameters

The 140DAI34000C is designed in a standard format, ensuring straightforward compatibility with Modicon Quantum racks and backplanes. It operates reliably within an ambient temperature range of 0°C to 60°C, making it suitable for various factory floor conditions. Weighing approximately 0.30 kg, the module is lightweight and easy to handle during installation.

Installation Guidelines
