More about selecting S7-1200 analog inputs parts

S7-1200 analog inputs for SIEMENS SIMATIC S7-1200

AI analog inputs convert sensor signals for processing in the PLC. Correct selection depends mainly on signal type, channel count and required resolution.

Typical applications and selection

AI analog inputs connect voltage, current, RTD resistance sensors and thermocouples. The measured-signal type, range and required accuracy determine module selection.

  • voltage and current ranges
  • RTD and thermocouple support
  • number of channels and required resolution
  • parameterisation and diagnostics in TIA Portal

How do you select the right version?

The most reliable method is selection by the complete SIEMENS order number. For a replacement, we also recommend verifying the hardware and firmware version, part function, station configuration and TIA Portal compatibility.

  • complete order number and required quantity,
  • function and technical parameters of the original part,
  • compatibility with the CPU, expansion modules and the project used.

New and refurbished parts from stock

For current S7-1200 parts, we primarily check availability of a new genuine SIEMENS item. Thanks to our wide warehouse network in Europe and worldwide, we can also check refurbished, discontinued and hard-to-find versions.

Frequently asked questions

Can I replace an analog input with another type?

The signal type and range, channel count and TIA Portal configuration must be verified.

How quickly can you deliver the part?

Lead time depends on the specific part and warehouse. With access to many warehouses, we normally arrange delivery within a few days; for urgent needs, express delivery within hours may be available. Call us immediately for urgent requests — selected parts can be sourced day and night.

Is the order number sufficient for an enquiry?

Yes. Ideally, send the complete number from the nameplate and the required quantity; a nameplate photo also helps with replacement or repair.

How to capture sporadic faults on Siemens S7 PLCs

How to capture sporadic faults on Siemens S7 PLCs

Sporadic faults on Siemens SIMATIC S7 PLCs are difficult to find using standard online diagnostics. In this article, we show how auto.spy analyzer helps capture signals, events and video on a single timeline and trace the root cause of the problem afterwards.
