The Kemo DIN rail mounted filters units combine Kemo's knowledge of signal filtering with a DIN rail case, screw connections, and a 24 V DC supply. With the combination of gain, easy installation, and a wide range of filter responses the Kemo DIN Rail filters are an easy solution to many industrial signal problems.
Filters are available to cover a wide range of applications, general purpose noise reduction, anti-aliasing, signal reconstruction, and notch filters to reduce unwanted frequencies, as well as traditional Butterworth and Bessel filters. Gain is set by easy access dip switches, with gain and offset trim. Input configurations are set by internal jumpers, the case opens without tools. Signal and power connections are made by standard screw terminals. 
The combination of easy of use, DIN rail industrial mounting, and a large range of filters and frequencies allows a very wide range of small signal problems to be solved using the Kemo DIN rail filters.
See our Applications section for a real problem solved using Kemo filters similar to the DIN Rail filters.
DIN Rail filters are available with 4-20mA input and output and 0-20mA input and output, please contact us for your detailed requirements.
Kemo have many years expertise in the field of small noisy signals, contact us if you have any questions, or require further information.
