7MH4980-2AA01, Siemens, SIMATIC S7-1500 DI 3 X 24V DC / DQ 4 X 24V DC, technology module

7MH4980-2AA01 is a digital input module made by Siemens for the system SIMATIC S7-1500 / ET 200MP. Important data of this variant include DI 3 X 24V DC / DQ 4 X 24V DC, RS485 / Ethernet, 24 V DC.

The description is compiled from the technical data contained in the source export. For industrial components, the full order code is decisive for correct selection, because individual variants of one series may differ in electrical design, communication, performance or functions.

Typical applications

A signal module expands the PLC assembly with digital or analogue inputs and outputs. It is used for connecting sensors, push buttons, limit switches, valves, contactors, analogue transducers and other peripherals. The number of channels, electrical design and type of measured or switched signal are decisive.

Technical specifications

Integration into the assembly

When wiring an I/O module, verify the signal type and level, common potentials, current load and protection method. For analogue modules, check the signal range, sensor type and required resolution. For digital outputs, verify the load type and electrical limits of the specific variant.

How to choose the right variant

First determine whether you need DI, DQ, AI or AO, then the number of channels, voltage or current level, or the type of temperature sensor. For outputs, distinguish between transistor and relay versions.

Kontrola kompatibility

When replacing or expanding an existing system, compare the original order number, product series, electrical connection, network interfaces and any project requirements. If any part of the MLFB code differs, it is necessary to verify whether the difference changes the function of the product.

Documentation and links from the source description

No usable external links are given in the source description. To find documentation, use the exact order code given above.

Related components

When completing the assembly, choose the power supply, CPU, signal modules, communication components, connectors, cabling or software according to the same system series and the requirements of the specific project. Confirm mutual compatibility according to the exact order codes.

FAQ

What kind of product is 7MH4980-2AA01?
According to the source data, this is a digital input module made by Siemens for SIMATIC S7-1500 / ET 200MP. The exact version of this variant is given in the technical table.

How do I verify that 7MH4980-2AA01 is the right variant?
Compare the full order number, product series, product type and all technical parameters that are decisive for your assembly.

Why is a similar product name not enough?
In industrial automation, a single character in the order code can mean a different interface, supply, number of channels, performance or licence variant.

What is most important when replacing an existing part?
The safest approach is to start from the exact order number of the original part and then verify electrical, mechanical and system compatibility.

Can the product be used in another assembly of the same series?
Only if the system requirements and technical parameters of the specific assembly match. The same product series alone does not guarantee compatibility.

Which technical data should I check before ordering?
At least the product type, supply, interface, number and type of channels or performance, and all other data listed in the technical parameters table.

How to proceed with integration into the PLC system?
When wiring an I/O module, verify the signal type and level, common potentials, current load and protection method. For analogue modules, check the signal range, sensor type and required resolution. For digital outputs, verify the load type and electrical limits of the specific variant.

How to choose between similar variants?
First determine whether you need DI, DQ, AI or AO, then the number of channels, voltage or current level, or the type of temperature sensor. For outputs, distinguish between transistor and relay versions.

Where can I find documentation for the specific version?
Use the exact order number 7MH4980-2AA01 and the links that were part of the source description, if listed below.

What should I do if I am not sure about compatibility?
Before ordering, compare the parameters with the original part or with the documentation of the whole assembly. For an unclear replacement, it is advisable to confirm the decision according to the specific application, not just the name.
