FAQ

Question?

What is the significance of the product version (E-Stand) *E07* on this module?

The product version, or ‘E-Stand’, indicates the hardware and firmware revision of the device. Version E07 is a specific release, and it’s important to ensure compatibility if you are replacing an identical module in an existing, validated safety system. Different versions may have minor changes that could affect system behavior.

Question?

Can I use this 3RK1205-0BE00-0AA2 module with a modern AS-i Master V3.0?

Yes, this module is specified for AS-i Specification V2.1 but is fully compatible with V3.0 AS-i masters. It will function correctly in a network with a newer master, although it will not support the extended features exclusive to V3.0 slaves.

Question?

What is the primary difference between this model and its successor, the 3RK1205-0BG00-0AA2?

The primary differences are typically related to internal component updates, improved diagnostics, or expanded certifications to meet newer standards. Functionally, they are designed to be largely compatible for replacement purposes, but it is always recommended to consult the technical documentation for any specific application changes.
