6ED1055-1MB00-0BA3, Siemens, LOGO! DM8 12/24R, 4 DI, 4 relay DO

Siemens LOGO! DM8 12/24R – digital expansion module, 4 DI and 4 relay outputs (6ED1055-1MB00-0BA3)

Siemens LOGO! DM8 12/24R is a digital expansion module for the LOGO! system 9. It is used to expand the LOGO! system 9 with additional inputs and relay outputs for sensors, contactors, valves and signalling. 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
Expansion by 4 digital inputs and 4 relay outputs.
Relay contacts switch up to 5 A with resistive and 3 A with inductive load.
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

Use it when the basic module does not have enough digital I/O and the system runs on a 12 or 24 V DC supply.

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.
