Schneider 140HLI34000 Latch Module | Quantum Fast Interrupt

Product Introduction

The Schneider Electric 140HLI34000 latch/interrupt module brings high-speed input capability to the Modicon Quantum automation platform. This 16-channel module captures fast digital events that standard input modules cannot detect. It handles signals from encoders, trip switches, and high-speed counters with exceptional precision. The module accepts 15 to 30V DC inputs and offers an ultra-fast response time of just 30 microseconds for On-Off transitions. Additionally, it provides internal reverse polarity protection up to 30V DC. This feature safeguards the module against accidental wiring errors. The 140HLI34000 operates as a standard format module that mounts directly on the Quantum backplane. It integrates seamlessly with your existing system architecture. Consequently, this module delivers the speed and reliability you need for demanding motion control and event-capture applications.

Technical Specifications

The 140HLI34000 offers impressive technical performance for high-speed discrete input applications. This module provides 16 fast isolated discrete input channels. The discrete input type is specifically categorized as fast isolated, meaning each channel offers electrical isolation from others. For input voltage, the absolute maximum stands at 30V DC. The voltage state 0 guarantee ranges from -3 to 5V, while the voltage state 1 guarantee spans 15 to 30V. For current, state 0 guarantee sits at 2 to 8 mA, and state 1 guarantee stays at less than or equal to 0.5 mA. These clear thresholds ensure reliable signal detection even in noisy environments.

Furthermore, the response time sets this module apart from standard input modules. The Off-On transition takes just 130 microseconds, while the On-Off transition takes an exceptionally fast 30 microseconds. This speed makes the 140HLI34000 ideal for capturing brief events and high-frequency signals. The module also includes internal reverse polarity protection in 30V, preventing damage from incorrect wiring. Isolation between channels reaches 500V for 60 seconds AC, and isolation between channels and the bus reaches 1780V for 60 seconds AC. The bus current requirement is 400 mA, and power dissipation calculates as 2.0 W plus 0.3 times the number of active points.

Mechanical and Environmental Parameters

The 140HLI34000 withstands demanding industrial conditions with ease. The ambient air temperature for operation spans 32 to 140 °F (0 to 60 °C). For storage, it endures temperatures from -40 to 185 °F (-40 to 85 °C). The module tolerates a relative humidity of 95% without condensation, making it suitable for humid factory environments. It operates reliably at altitudes up to 5000 meters. This module holds numerous global certifications, including UL 508, DNV, GOST, CSA Class 1 Division 2, UL, FM Class 1 Division 2, and C-tick. Therefore, it meets safety and performance standards for international installations. The unit demonstrates strong resistance to electrostatic discharge at 4 kV for contact and 8 kV for air per IEC 801-2. Its resistance to electromagnetic fields reaches 9.1 V/m (10 V/m) across 80 to 2000 MHz per IEC 801-3.

Installation Guidance

Installing the 140HLI34000 latch/interrupt module requires careful attention to system architecture. First, ensure the backplane supports local architecture mounting. The standard format module slides into any available slot in the Quantum rack. Push it firmly until the connectors seat properly and the locking mechanism engages. Next, connect your field wiring to the appropriate terminal block or CableFast accessory. Each of the 16 input channels accepts a 15 to 30V DC signal from your fast-switching devices. Pay close attention to polarity, as these are DC inputs. Although the module includes reverse polarity protection, correct wiring ensures optimal performance. After securing all connections, apply power to the rack. The module will communicate with the processor via the backplane. Finally, configure the latch and interrupt functions in your software. The 140HLI34000 captures events and generates interrupts for time-critical processing tasks.
