6ES7144-4JF00-0AB0 is identified by Siemens as an Analog Input Module within the Simatic S7 family.
For replacement planning, a digital input module receives discrete on/off states from field contacts and devices, then makes those states available to the controller for monitoring, sequencing, alarms, and interlocks. Its role should remain distinct from that of similarly named assemblies.
Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The installed revision should be confirmed before the product is applied.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Final selection should be based on the plant's controlled-equipment records.
