Product details

The Siemens 6AG1591-1BA01-2AA0 is a SIPLUS S7-1500 front flap V2 CPU 70 mm — a replacement display for certain SIPLUS CPUs (1515F through 1518F PN/DP variants). It carries conformal coating and is rated for a horizontal installation range of -20 to +60 °C, with a max ambient of 70 °C and a min of -40 °C (the vertical installation range is more limited). This is the part to specify if the standard 6ES7591-1BA01-0AA0 won't survive the washdown or salty air.

Lifecycle stage is marked as current — this is an active product, not a last-time-buy or on the way out. That means the replacement display is still in standard distribution and will be built to order. No imminent obsolescence to track.

Frequently asked questions

What is the maximum operating temperature?

The max ambient temperature is 70 °C (horizontal installation max 60 °C). Below 0 °C display response may be slower.

What is the minimum operating temperature?

The min ambient temperature is -40 °C (horizontal installation min -20 °C including condensation/frost).

Does this part replace the standard 6ES7591-1BA01-0AA0?

Yes, it is based on that standard unit but adds conformal coating and a wider environmental resistance for harsh conditions.
