Analog Modules - Analog input SM 331

The analog input modules convert analog signals from the process into digital signals for processing within the PLC. The modules feature: Resolution from 9 to 15 bits + sign (for different conversion times), configurable Different measuring ranges; the basic current/voltage range settings are adjusted mechanically via measurement range modules. Fine adjustments are made with the STEP 7 Hardware Configuration tool on a PG.
