Process Instrumentation
The pH502 series of controllers offer many features to increase the level of control available in your plant These instruments can be configured to utilize P, PI, PID controlling With this feature, the pH502 takes the place of three instruments that only allow one configuration each The pH502 line includes models that incorporate control through analog output to drive any compatible device, such as an electrovalve or pump The solid state relay is available to ensure maximum life of the switching device Each model has a differential input for a grounding bar to extend electrode life
Fail Safe Alarm System protects against power interruption or line failure 1, 2 or 3 point automatic calibration and manual or Automatic Temperature Compensation complete the features of this controller
