Schneider 140DAI54300C 115VAC 16-Channel Input

140DAI54300C Modicon Quantum Discrete Input Module

Product Introduction

The 140DAI54300C from Schneider Electric functions as a discrete input module within the Modicon Quantum PLC family. This module captures 16 digital input channels at 115 VAC, making it an excellent choice for applications that use higher voltage AC signals from field devices. Its robust design, including conformal coating, ensures dependable performance even in challenging environmental conditions.

Key Technical Specifications

The Schneider Electric 140DAI54300C provides 16 discrete input channels that operate at a nominal 115 VAC input voltage. This voltage level makes it particularly suitable for regions and applications where 110-120 VAC control circuits are common. For addressing purposes, the module requires 1 input word in the processor's memory map.

The input current ranges from 11.1 to 13.2 mA per channel, delivering consistent signal detection. A maximum leakage current of 2.1 mA helps minimize false triggering from residual current. The module draws a bus current of 180 mA from the rack backplane, with maximum power dissipation rated at 5.5 W, reflecting its efficient power consumption.

Protective Treatment and Durability

The 140DAI54300C features a protective conformal coating that shields the circuit board from moisture, dust, and chemical contaminants. This coating significantly enhances the module's reliability in harsh industrial settings. It is particularly valuable in applications exposed to humidity or airborne particles.

Standards and Compliance

This input module carries the CE marking, confirming its conformity with essential European health, safety, and environmental protection requirements. It also 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 safety.

Mechanical and Environmental Parameters

The 140DAI54300C follows a standard format, ensuring seamless 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. At approximately 0.30 kg, the module is lightweight and easy to handle during installation.

Installation Guidelines

Installing the 140DAI54300C involves a few straightforward steps. First, power down the rack completely to ensure safe handling. Next, align the module with the guide rails inside the Quantum chassis. Then slide it firmly into position until the backplane connector engages fully. Finally, secure the module by tightening the retaining screws. After installation, you can connect your field devices to the front terminals.
