Product details

Delta vs standard 6ES7952-1AS00-0AA0

The 6AG1952-1AS00-7AA0: This SIPLUS derivative adds conformal coating and widens the operating range from the standard to -25–70 °C. The coating supports harmful gas concentrations up to EN 60721-3-3 class 3C4, salt spray, and oil.

Installation notes

Mounts in S7-400 CPU slot as long-design RAM card. No field-wiring connections – plugs directly into the backplane connector. Ensure battery-backed RAM or external power hold-up if data retention on outage is required.
