Siemens 6ES7331-7PF11-0AB0 is an 8-channel analog input module for the S7-300 rack. It handles thermocouple inputs only — supports types B, C, E, J, K, L, N, R, S, T, U. No RTD, current, or voltage inputs. Dimensions are 40 mm wide, 125 mm height, 120 mm depth. That depth is standard for S7-300, so it slots into the same backplane as any other module in the series. The Cu 10 and Pt 100 input options are not supported — this is thermocouple only, so if your BOM calls for RTD or 4-20 mA, this is not the module.
