+The KTA-289 can take a voltage signal, from below 0.1V to above 30V and convert it to a 4-20mA signal. The full scale of the input signal needs to be below 2.3V or above 4.9V.To convert voltage signals with full scale voltage between 2.3V and 4.9V it is recommended to use 5V as the full scale range, or contact Ocean Controls with your requirements.

Configuration

The KTA-289 must be configured to work for the voltage range of your application. To do this a voltage source ofthe full scale voltage is required.Follow these steps to configure the unit for any voltage range.When using with signals with full range greater than 3.3V move the switch to the Divide position.When using with signals with full range lower than 3.3V move the switch to the Amplify position.Short out INPUT to GND and adjust the 4mA adjustment potentiometer until 4mA is seen on the OUTPUT.Input a maximum range signal to the INPUT pin and adjust the 20mA adjustment potentiometer until 20mA is seenon the OUTPUT pin, the KTA-289 is now ready for use.
