Product Description:
The Beckhoff's manufactured KL3404 Analog Input Module is specifically designed for accurate acquisition of analog voltage signals from four single-ended input channels. This module has a broad input signal voltage range of -10 V to +10 V to enable it to accommodate both negative and positive voltages from a wide range of industrial sensors and devices.
This input module guarantees a measurement error of below ±0.3%, compared to the full-scale value, to ensure that even slight changes in input voltage are measured accurately and reliably without much deviation. The internal resistance of the KL3404 input module is over 130 kΩ to reduce the load effect on the connected signal sources. With 12-bit resolution across the entire ±10 V range, this input module provides precise signal representation. The conversion time of around 2 milliseconds allows for fast sampling in this module and facilitates real-time monitoring. When operating within a 0–10 V range, this module provides an effective 11-bit resolution with high accuracy even at low input levels. This module features a single-ended input technology, which enables simple wiring for ground-referenced applications.
This module is compact and has dimensions of 12 mm x 100 mm x 68 mm (W x H x D) to achieve high-density installation in restricted space. With a weight of about 75 grams, the KL3404 input module puts minimal mechanical stress on the assembly of the DIN rail. The installation of this module is done directly on a 35 mm DIN rail conforming to EN 60715 by using a secure lock mechanism to be used stably in industries. The power to this module is delivered through the K-bus, which minimizes the installation hurdles and cabling complexity in control panels.
Frequently Asked Questions about KL3404:
Q: How does the >130 kΩ internal resistance of the KL3404 benefit signal integrity?
A: It minimizes the load on the signal source, preserving the accuracy of the measured voltage. This helps maintain reliable performance in sensitive analog circuits.
Q: Why does the KL3404 use single-ended technology for its voltage inputs?
A: Single-ended inputs simplify wiring and reduce costs for applications needing grounded signal references. It also enhances compatibility with many standard industrial sensors.
Q: How does the 2 ms conversion time of KL3404 improve system performance?
A: Faster conversion enables near real-time signal acquisition. This reduces system response delays in time-sensitive automation tasks.
Q: What advantage does the 12-bit resolution of the KL3404 provide in analog measurements?
A: A 12-bit resolution offers 4096 discrete levels, ensuring fine-grained analog signal detail. It supports high-precision control and monitoring in industrial systems.
Q: How does the KL3404 ensure installation security on a 35 mm DIN rail?
A: It uses a mechanical lock according to EN 60715 standards. This lock prevents vibration-induced displacement in industrial environments.
