Schneider Electric 140HLI34000 Latch/Interrupt Module: Application-Focused Overview

The Schneider Electric 140HLI34000 Latch/Interrupt Module is a critical component for enhancing input functionality in industrial control systems. With its standard-format design and 16 discrete inputs, this module is engineered to meet the diverse and demanding requirements of modern automation tasks across various sectors, including material handling, packaging, and textile machinery.

Enhanced Input Capabilities for Robust Signal Processing

In high-speed industrial environments, reliable signal detection is paramount. The 140HLI34000 is equipped with fast isolated discrete inputs that ensure accurate signal representation under varying operational conditions. It supports an absolute maximum input voltage of 30 V DC, with defined voltage states of -3 to 5 V for state 0 and 15 to 30 V for state 1. This precision allows engineers to confidently integrate the module into systems requiring stringent input specifications.

Rapid Response Times for Real-Time Control

The module's impressive response times—130 µs for Off-On transitions and 30 µs for On-Off transitions—enable swift input processing. This capability is essential for real-time control applications, allowing operators to react promptly to changes in the production environment. Such responsiveness is particularly beneficial in dynamic settings where operational efficiency and safety are critical.

Built-In Protection Mechanisms for Increased Reliability

The 140HLI34000 features internal reverse polarity protection at 30 V, safeguarding the module against potential damage from incorrect wiring. This built-in protection, combined with robust isolation ratings of 500 V AC for 60 seconds between channels and 1780 V AC for 60 seconds between channels and the bus, enhances electrical safety. These characteristics are vital for maintaining system integrity and minimizing downtime due to electrical faults.

Efficient Power Management for Sustainable Operations

With a low bus current requirement of 400 mA and efficient power dissipation of 2.0 W plus an additional 0.3 times the number of points on the module, the 140HLI34000 is designed to optimize energy consumption. This efficiency not only reduces operational costs but also contributes to a more sustainable industrial process, making it an ideal choice for engineers focused on energy management.

Seamless Integration and Installation

Designed for straightforward installation, the 140HLI34000 module mounts directly onto a backplane, facilitating easy integration into existing control architectures. Its compliance with CE marking ensures adherence to European safety standards, providing engineers with the assurance
