Product details

The Siemens 6AG1591-1AA01-2AA0 is the SIPLUS hardened version of the standard S7-1500 front flap V2 (order code 6ES7591-1AA01-0AA0), with conformal coating and an extended ambient temperature range for horizontal installation of -20 °C to +60 °C. It serves as a replacement display for SIPLUS CPUs including the CPU 1511 (F)-1 PN and CPU 1513 (F)-1 PN.

Temperature range and installation limits

Below 0 °C, legibility and dynamic content may degrade. For vertical installation the limits are tighter – not explicitly given for this variant, but the horizontal figure governs for most panel layouts. Above 2 000 m altitude, derate the maximum ambient temperature by 10 K per 1 500 m up to 5 000 m.

Compared to 6ES7591-1AA01-0AA0, the SIPLUS variant adds conformal coating, a -40 °C minimum temperature, and resistance to coolants and lubricants.

Frequently asked questions

What is the closest functional second-source to this part?

The direct functional counterpart is the standard version 6ES7591-1AA01-0AA0. The SIPLUS variant adds conformal coating and a wider temperature range. I/O modules like 6AG1231-5QD32-4XB0 are not substitutes; they serve different functions in the S7-1500 system.

What temperature range does this part support in horizontal installation?

Horizontal installation range is -20 °C to +60 °C (including condensation and frost at the lower limit). The component as such is rated -40 °C to +70 °C, but mounting orientation and altitude derating apply.

What compliance documentation is available for this part?

Evidence indicates compliance with IPC-CC-830A conformal coating class A, ANSI/ISA-71.04 environmental levels (GX, LC3, LB3), and resistance to coolants and lubricants per EN 60721-3-3 class 3C4. The specific certificates (CE, UKCA, etc.) are manufacturer-declared; request the declaration of conformity from your distributor.
