Product details

The Siemens 6AG1952-1AM00-7AA0 is a SIPLUS S7-400 MC RAM 4 MB memory card, built on the standard 6ES7952-1AM00-0AA0 with conformal coating and an extended temperature range of -25 to 70 °C. It's designed for S7-400 CPUs that need to run in harsh or unconditioned environments.

Delta vs. standard S7-400 RAM card

This SIPLUS version adds conformal coating to the standard card and operates at -25 to 70 °C.

Integration into S7-400 rack

This is a long-design RAM card for S7-400 CPUs. It plugs into the memory slot on the CPU or the programming device interface. No additional wiring needed. Altitude derating: up to 2 000 m at full temp range; between 2 000 and 3 500 m, derate max temperature by 10 K; above 3 500 m to 5 000 m, derate by 20 K.

Frequently asked questions

What temperature range does this memory card support?

It operates from -25 °C to 70 °C, which is wider than the standard S7-400 RAM card.

What is the memory capacity?

It has 4 Mbyte of RAM.

Does this card replace the standard 6ES7952-1AM00-0AA0?

It is a ruggedized variant of the standard card, not a direct electrical replacement due to the wider temperature range and conformal coating, but it fits the same slot.
