6AG1055-1MM00-7BA2, Siemens, SIPLUS LOGO! AM2 AQ, 2 AQ

6AG1055-1MM00-7BA2 SIPLUS LOGO! AM2 AQ – 2 AQ

6AG1055-1MM00-7BA2 is a Siemens expansion module in the SIPLUS version for SIPLUS LOGO! 8 (0BA2).

6AG1055-1MM00-7BA2 SIPLUS LOGO! AM2 AQ: 2 AQ (0–10 V, 0–20 mA, 4–20 mA), -40 … +70 °C. Verify the compatibility of the assembly.

What the SIPLUS designation means

SIPLUS is a ruggedised version of a standard Siemens part. The electronics, terminals, dimensions and programming remain the same; what is added is protective coating of the assembled board (conformal coating) against condensation, icing and aggressive gases, and an extended temperature range. It is based on the standard part 6ED1055-1MM00-0BA2 (LOGO! AM2 AQ).

A project from LOGO! Soft Comfort runs on both the SIPLUS and the standard version without modification. The coating applies to the board, not the housing — the degree of protection does not change and the part still belongs in a switchboard.

Technical specifications 6AG1055-1MM00-7BA2

Which assembly it belongs to

Combine the module only with a Siemens LOGO! basic unit of the same generation. Verify the supply voltage and the available capacity of the assembly.

SIPLUS and standard parts can be combined in one assembly. The temperature range of the whole assembly is then determined by the weakest part — if the enclosure as a whole is to operate in the extended range, all parts in it must be SIPLUS versions.

Typical applications

• Adding inputs and outputs to a LOGO! assembly operated in the extended temperature range.
• Unheated switchboards and outdoor enclosures in year-round operation.
• Container and mobile solutions where the temperature in the enclosure follows the surroundings.
• Plants with condensation or a corrosive atmosphere — wastewater treatment plants, chemicals, agriculture.
• Cold storage and freezer plants.
• Processes where the control system is installed outside a heated building.

What to watch out for when choosing

• Verify that the application really needs SIPLUS — the price difference compared with the standard version is considerable and you pay for the temperature range and coating, not for functions.
• Combine the module only with a basic unit of the same generation.
• The range of the assembly is determined by the weakest part — the basic unit and power supply should also be SIPLUS.
• The range -40 … +70 °C applies to this specific code. Versions with and without display have different ranges — do not transfer the value between them.
• Compare the full order number. A similar name or appearance of the product is not enough; SIPLUS and standard versions look almost identical.

Frequently asked questions

What is the difference between 6AG1055-1MM00-7BA2 and 6ED1055-1MM00-0BA2?

Functionally none. 6AG1055-1MM00-7BA2 is the SIPLUS version – it has a coated board and an extended temperature range. Inputs, outputs, dimensions, terminals and program are identical.

Can I use 6AG1055-1MM00-7BA2 as a direct replacement for 6ED1055-1MM00-0BA2?

Yes, it is a direct one-for-one replacement. The other way round, this only applies where the environment matches the narrower catalogue range of the standard version.

What temperature range does 6AG1055-1MM00-7BA2 operate in?

-40 … +70 °C, with a start-up temperature from -25 °C. The range applies to this specific code, not to the whole series.

Does the board coating mean the part is waterproof?

No. The coating protects the assembled board against condensation, icing and aggressive gases. The housing protection does not change and the part belongs in a switchboard.

Which generation does the product belong to?

Order number 6AG1055-1MM00-7BA2 is listed in this catalogue as SIPLUS LOGO! 8 (0BA2). Before combining different generations, verify the compatibility of the whole assembly.
