Simatic S7-1200 compact controller offers high-density, four- and eight-channel modules. Combined with the Step 7 Basic engineering software, users can configure up to 16 separate PID loops per CPU. Built-in autotune and a PID commissioning interface are designed to simplify installation and startup. The SM 1231 series eight-channel analog input module supports industry standard unipolar 0-10 Vdc, 0-5 Vdc, 0-20 mA and bi-polar +/- 5 Vdc, +/-2.5 Vdc input signals. The SM 1232 series four-channel analog output module supports both 0-10 Vdc and 0-20 mA output signals. All output channels support higher resolution 14 data bits plus sign. The TC four-channel thermocouple temperature input module supports seven different thermocouple sensor types and +/-80 mV input signals. The four-channel RTD temperature input module supports eight different RTD sensor types and 150-Ohm, 300-Ohm, and 600-Ohm resistance inputs. The new analog and temperature modules can be DIN-rail or panel mounted and easily connect to the right-side backplane of an S7-1200 CPU. All S7-1200 hardware modules are certified with industry standard agency approvals including CE, cUL US, Factory Mutual Class I, Div. 2, ATEX for Hazardous Locations and C-Tick.
