Analog input configuration and procurement checks
Siemens 6ES7331-7KB02-0AB0 is an isolated SIMATIC S7-300 SM 331 analog input module with two channels and selectable 9, 12 or 14-bit resolution. The verified input options support voltage, current, thermocouple and resistor signals, with alarm and diagnostic functions. The module uses one 20-pole connection and can be removed or inserted with an active backplane bus. Buyers should verify sensor type, range, wiring, resolution, diagnostics, connector and the complete suffix before replacement. Stockoems condition, availability and warranty are commercial information rather than Siemens commitments.
