0/4 ... 20 mA monitoring 
Description 
With the aid of an analog module, SIMOCODE pro is capable of measuring and monitoring 
further process variables as desired. For example, the fill level can be monitored to protect a 
pump against dry operation, or a differential pressure transducer can be used to monitor the 
degree of pollution in a filter. If the fill level undershoots a specified level, the pump can be 
switched off and, if a specific differential pressure value is exceeded, the filter must be 
cleaned.
