Product Description:

The KL3051 is an analog input module designed for precise current measurement in industrial automation applications. This module features a single input channel, capable of handling signal current ranges from 4 to 20 mA. It's engineered to accurately monitor current signals, providing reliable data for control systems; its robust design ensures dependable performance in demanding industrial environments. The module's accuracy is demonstrated through its impressive measurement error of under ±0.3%, relative to full scale, further guaranteeing the reliability of current readings in diverse operational conditions.

The KL3051 boasts an internal resolution of 12 bits, enabling highly detailed and precise measurements; this ensures even slight variations in current are captured, so the module is suitable for applications demanding high accuracy. The module requires a 24 V DC power supply, connected via power contacts, facilitating easy integration through widely accepted compatible standards. With a typical current consumption of 65 mA from the K-bus, the KL3051 balances performance with power efficiency in its application. The input has a bit width of 1 x 16 bit data (1 x 8-bit control/status optional) in the process image. The modules also offers surge voltage resistance of max. 35 V, ensuring protection against voltage spikes and disturbances through robust engineering.

The KL3051 analog input module can reliably operate in temperatures ranging from 0 to 55°C making it suitable for many industrial environments through various degrees of environmental control. For storage, this can be kept in temperatures ranging from -25 to +85°C, ensuring its durability during transport and storage. The module has an internal resistance of 80 Ω plus forward voltage drop of approximately 0.7 V. Because of its construction, it ensures stable and reliable readings through stable resistance.
