Model 247's are designed to provide a voltage output, standard setup is 0-5 Vdc out, but the unit can be configured to provide outputs from -10 to +10 Vdc out and anything in between. The 247 series can be built to many custom configurations, and with the quality and reliability you expect from Viatran, they are built to last for a very long time.
