If you have ever tried to use the LM2917 frequency to analog converter IC you soon find that you are
mucking around trying to find the right balance between ripple, and max frequency and you end up
Our Dual frequency to analog converter allows you to easily convert up to two frequency signal streams to an analog voltage signal
The KTA-245 is not designed for unlimited frequencies but for most applications it is suitable. 60KHz
is combined maximum frequency of the two frequency inputs. ie. If channel 1 is 60KHz you cannot
use channel 2, but if channel 1 is 40KHz the maximum for channel 2 is 20KHz. Realistically, most
signals will be in the 10KHz or below range.
To set up the two ranges of the analog outputs there are four switch blocks on the PCB. A rotary
switch sets the base frequency and a dual DIP switch sets the multiplier
For ease of installation, the KTA-245 unit can be supplied with DIN rail mounting clips, this has part
* Frequency range set by rotary and DIP switches.
* Frequency range is from 0 to 60KHz for one frequency input.
* Opto isolated inputs available voltage signal can range from 0-5V to 0-24V or be NPN or PNP signal.
* The pulse stream can bypass opto-isolator inputs and can be 0 to 5V signal or a NPN signal.
* Output Ranges easily adjustable from 0-1.5V to 0-15V
* 12 to 15VDC powered.
* DIN Rail Mount Option
* All external connections are via screw terminals.
Dimensions 72(L) x 65(W) x 24(H)mm
The KTA-245 has been used to convert engine RPM's to an analog signal to connect to our Labjack Data Acquisition units
