6ED1055-1MF00-0BA3, Siemens, LOGO! AM4, 2 AI, 2 AO

Siemens LOGO! AM4 AI/AQ – analogue expansion module 24 V DC with 2 AI and 2 AO (6ED1055-1MF00-0BA3)

Siemens LOGO! AM4 AI/AQ is an analogue expansion module for the LOGO! system 9. It is used for processing analogue sensors and controlling frequency inverters, valves, controllers and other analogue actuators. It mounts on a 35 mm DIN rail and, thanks to its width of two module units, integrates easily into a compact switchboard.

Key advantages
One module adds 2 analogue inputs and 2 analogue outputs.
Selectable voltage and current ranges make it easier to connect industrial sensors and actuators.
Compact width of 35.5 mm saves space on the DIN rail.
Protection IP20 and operation from −20 to +55 °C.

When to use the module

The module combines analogue inputs and outputs in one device; it is not designed for direct connection of resistance thermometers Pt100.

Which assembly it belongs to

Connect the expansion module to a compatible Siemens LOGO! control module 9. Verify the generation, supply, signal type and available capacity of the assembly. Create the configuration in LOGO! Soft Comfort.

Frequently asked questions
Is the module designed for expanding the LOGO! basic unit?

Yes. It is an expansion I/O module of the new LOGO! series 9. When modernising an older assembly, verify the hardware compatibility of the whole configuration.

How is the module mounted?

On a standard 35 mm DIN rail; the device occupies a width of 35.5 mm, i.e. two module units.
