I/O modules added to micro PLC line

New I/O modules have been added to the SIMATIC S7-200 micro PLC product line. The EM231 series eight-channel analog input module supports industry standard unipolar 0-10 Vdc; 0-5 Vdc; 0-20 mA and bipolar +/- 5 Vdc; and +/-2.5 Vdc input signals. The EM232 series four-channel analog output module supports both 0-10 Vdc and 0-20 mA output signals.
