KL3454
by Beckhoff
The Beckhoff KL3454 is a high-performance analog input module in the KL Analog Input Modules series, designed and manufactured by Beckhoff for precise current signal monitoring. This terminal provides 4 inputs with a 12-bit resolution and supports signal currents of 4–20 mA for accurate process control. As part of an EtherCAT-based system, the KL3454’s primary application is in industrial automation where it acquires multiple current signals simultaneously, delivering reliable, high-speed data transfer and integration.
In-depth technical specifications underscore the KL3454’s robust design. The module features a rapid conversion time of ~2 ms for each channel, ensuring swift response in time-critical operations. Its internal resistance remains below 85 Ω, minimizing voltage drop and promoting signal fidelity. Measurement uncertainty is kept under ±0.3% (relative to full scale), guaranteeing precise readings across the input range. Signal input type options include both single-ended and differential configurations, providing flexibility in sensor connection. Surge voltage resistance up to 30 V DC and continuous overvoltage protection of 35 V DC safeguard connected devices from electrical transients. The module is powered directly via the K-bus, simplifying cabinet wiring and reducing auxiliary power requirements.
Additional features enhance the KL3454’s compatibility, durability, and efficiency. Operating between -25…+60 °C and storing safely from -40…+85 °C, it meets the demands of harsh industrial environments. Current consumption on the K-bus is typically 85 mA, optimizing energy usage in large-scale installations. The unit holds multiple international approvals and markings — including CE, CCC, UL, ATEX, IECEx, and DNV GL — and complies with RoHS standards, ensuring both performance integrity and environmental safety. Ideal for process automation, factory controls, and machinery monitoring, the Beckhoff KL3454 delivers precise analog acquisition, robust protection, and seamless EtherCAT integration, driving operational efficiency in industrial applications.
