Product Description:

Beckhoff KL Analog Input KL3404-0018 comes from the highly acclaimed KL Analog Input Series. This portable instrument is built with accuracy and power in mind for use in different applications which makes it suitable for application in industries that need data acquisition systems. The module uses four input channels, and each input channel is designed to accept a signal voltage of ±10V to enable measurement of both positive and negative voltage signals. To enable accurate representation of data, the KL3404-0018 has a 12 bit resolution which makes it to stand out. This high resolution is particularly important for applications where even small differences in the signal are possible. The conversion time of the module is estimated to be at about 2 milliseconds enabling it to provide quick response in systems that require timely data conversion.

The measurement uncertainty is less than ±0.3% allowing the user to have confidence in the readings when making important decisions. In addition, it has an input impedance over 130 kΩ to reduce loading effects on the connected sensors and guarantee that the measurements are influenced by the input impedance of the module.

Having a mass of as small as seventy five grams, this is a mini module that is not only lightweight but also relatively rigid in construction for integration in mostly industrial settings. Contrary to its small size, the strip is not inferior to other devices in its functional capabilities and can easily integrate into existing systems, with few changes needed to adapt it. In automation, process control, or any other application that requires analog input, the Beckhoff KL3404-0018 is proven to be very efficient.
