We supply SIEMENS SIMATIC S7-1500 and ET 200MP analog input modules for measuring voltage, current, RTD, thermocouples and HART signals. Select the module by its 6ES7531-... order number, or send us the part number and we will check the price and availability.
Do you have a 6ES7531-... order number?
Send us the full order number, required quantity and, if available, a photo of the nameplate. We will check the availability of a new or refurbished part and, if required, the repair options.
More about SIMATIC S7-1500 analog inputs and how to choose the right module
SIEMENS SIMATIC S7-1500 analog input modules
SIMATIC S7-1500 analog input modules convert analog signals from sensors and transmitters into values that can be processed by the PLC program. They are used, for example, to measure temperature, pressure, flow, level, position and other process variables.
Voltage and current
Modules for standard analog signals such as 0–10 V, ±10 V, 0–20 mA or 4–20 mA, depending on the specific module version.
RTD and resistance sensors
Direct connection of resistance temperature sensors and other supported resistive measuring elements.
Thermocouples (TC)
Selected analog input modules allow direct measurement of thermocouples, particularly for temperature measurement.
HART
Analog input modules with HART support are also available for communication with intelligent process instruments.
How to choose the right S7-1500 analog input?
The safest way is to select the module using the complete SIEMENS order number. When replacing a module with another type, check in particular:
- signal type – voltage, current, resistance, RTD or thermocouple,
- number of analog input channels,
- resolution and required measurement accuracy,
- conversion speed and required measurement time,
- diagnostic and technological functions,
- HART communication requirements,
- compatibility with the hardware configuration in TIA Portal.

New and refurbished parts from stock
For current SIMATIC S7-1500 modules, we primarily check the availability of a new original SIEMENS part. We use an extensive network of European warehouses with more than 900,000 industrial spare parts.
This also enables us to check refurbished, older or hard-to-find module versions. If you cannot find a particular part in our e-shop, send us its order number and we will check availability.
Repairs of SIEMENS SIMATIC S7-1500 modules
If you have a faulty analog input module, you can send it to us for diagnostics and repair. Repairs are carried out in specialised repair centres in Europe with which we have established long-term cooperation.
These repair centres specialise in industrial electronics, and repaired parts are functionally tested before being returned to the customer.
SIPLUS for demanding environments
Selected SIPLUS versions are also available for applications operating under more demanding environmental conditions. You can find them in the separate S7-1500 analog input subcategory.
Frequently asked questions
Yes. Ideally, send us the complete SIEMENS order number from the nameplate, for example 6ES7531-7KF00-0AB0, together with the required quantity.
Yes. We also check the availability of other parts in European warehouses. Send us the order number and we will check the supply options.
Yes. Send the faulty module to FOXON. We will arrange diagnostics, repair and subsequent functional testing at a specialised European repair centre with which we have long-term cooperation.
Not always. The number of channels, signal type, measuring ranges, resolution, module functions and hardware configuration in TIA Portal must be checked.

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.
