New analog input solid state proportional controllers
CARLO GAVAZZI is proud to announce the launch of their new Single Phase RGx1P Proportional Output Controllers. With a typical solid state relay, the output from measuring or monitoring devices is an analog signal that needs to be converted to a discrete signal to control a ‘common’ solid state relay. This can be costly, complicated […]
