SIPLUS S7-300 · ANALOG INPUT
Eight-channel current input module with conformal coating for extended environmental operation.
Siemens 6AG1331-7TF01-7AB0 is a SIPLUS S7-300 SM 331 analog input module based on 6ES7331-7TF01-0AB0 and protected by conformal coating. The official data specifies eight current inputs for 0/4 to 20 mA signals, 24 V DC supply, maximum 16-bit resolution including sign, 240 ohm input resistance and shielded cable lengths up to 800 m. Siemens rates operation from -25 to +70 °C. Replacement planning should verify the full SIPLUS suffix, front connector and wiring, current range, integration time, diagnostics, grounding, environmental qualification, rack position and STEP 7 hardware configuration.
