The Beckhoff KL3444 is a compact and versatile four-channel analog input terminal designed for seamless integration into the Beckhoff Bus Terminal system. This terminal is engineered to process signals in the range of 0 to 20 mA, making it an ideal solution for a variety of industrial control and monitoring applications.
Each channel of the KL3444 boasts an internal resistance of less than 85 Ω and can handle a common-mode voltage of up to 30 V, ensuring reliable and accurate signal acquisition. With a 12-bit resolution and a swift conversion time of approximately 2 ms, the KL3444 delivers precise data with minimal delay, enhancing the efficiency of automated processes.
The terminal's total measuring error remains below ±0.3% of the full scale value, which is a testament to its precision and reliability across the entire operating temperature range. The KL3444 is also designed with surge voltage resistance up to 30 VDC and electrical isolation of 500 V between the K-bus and signal voltage, providing an additional layer of protection for sensitive components.
Installation is straightforward, as the KL3444 is designed to mount on a standard 35 mm mounting rail in accordance with EN 60715. Its dimensions are approximately 15 mm x 100 mm x 70 mm, and it weighs around 55 g, making it a compact solution that can fit into various control cabinet configurations without taking up excessive space.
The terminal operates reliably within an ambient temperature range of 0 °C to +55 °C and can be stored in temperatures ranging from -25 °C to +85 °C. It is also designed to withstand the rigours of industrial environments, meeting the vibration and shock resistance standards set out in EN 60068-2-6/EN 60068-2-27.
For system integrators and automation professionals in the UK looking for a dependable and accurate analog input solution, the Beckhoff KL3444 represents a smart choice that combines performance, durability, and ease of use.
