DIN Rail Mounting Filters Ease Signal
Conditioning
The combination of configurable input gain and a flexible range of signal filters makes the Kemo DR range suited to noise reduction, anti-aliasing, band limiting and signal optimisation.
The Kemo DR range of DIN rail mounting filters offer a fast, easy-to-install solution to signal conditioning in electrically noisy industrial environments The combination of configurable input gain and a flexible range of signal filters makes the devices ideally suited to applications such as noise reduction, anti-aliasing, band limiting and signal optimisation in industrial data-acquisition, measurement and control systems

Car navigation and telematics tested automatically
Today's automobile is already a vast network of interconnected silicon chips, controlling everything from airbags to engines operations. Alfautomazione has systems to test them.
The new family is based on the established Kemo CardMaster 1 filter carrier card, and two versions are available: the DR 1200, offering a fixed factory-set frequency from 1 Hz to more than 500 kHz; and the DR 1600, in which the frequency can be set in 255 steps by DIP switches, with versions covering the frequency range from 0.2 Hz to 127.5 kHz.
A range of filter responses is available, including low-pass, high-pass and notch filter characteristics.
Both versions have configurable input gain, set by externally accessible DIP switches, from 0 to +60 dB (?1000), AC/DC input coupling, single-ended/differential inputs and a 24 V IEPE transducer power supply that is adjustable to 10 mA.
The signal zero voltage is floating with reference to the power supply, allowing flexibility in system earthing.
The differential input allows use with 4-20 mA systems in conjunction with a current-sense resistor.
The DR unit measures 45 x 78 x 110 mm, and fits onto a 35 x 15 mm DIN rail.
Screw terminal connectors are fitted.
