Product Description:

The KL3408 from Beckhoff Technology works as a robust 4-channel device to measure precise voltage levels in automated industrial applications.

With its place in Beckhoff's KL analog input module series, the device makes accurate digital control possible through the Beckhoff Bus Terminal platform. The module has four separate analog inputs that measure voltage between -10 V to +10 V on each channel. The device delivers 12-bit resolution, which precisely transforms analog signals into a digital format for automated monitoring and control duties. The terminal contains a built-in input filter that reduces high-frequency noise and keeps measurements steady when placed in power-dense locations with a cutoff setting at 30 Hz. The KL3408 captures signals quickly in just 10 milliseconds to work well with existing real-time monitoring systems. This measurement module shows reliable results within 0.3% measurement error across its entire scale range by design.

The K-Bus connection delivers this terminal 50 mA of power effortlessly while saving energy for large systems. The device is wired with just two connections to make installation and setup simpler. The component physical design takes up limited space at 15 mm wide by 100 mm high by 68 mm deep to make the most of the cabinet space available. Under ideal conditions, it performs well from 0°C to 55°C and retains functionality through temperature swings from -25°C to 85°C. The module receives CE, UL, ATEX, and Ex approval to work reliably in safe industrial settings, plus regular non-hazardous areas. It can be purchased at Wake Industrial with a one-year warranty.
