Engineering Advantages

Seamless Failover Capability
Supports real-time memory mirroring between primary and secondary CPUs, ensuring instantaneous takeover by the backup controller in the event of a failure.

Ultra-Compact Footprint
The compact 15 cm design minimizes cabinet space requirements, enabling redundant system deployment even in constrained or legacy enclosures.

Dedicated Redundancy Link
Incorporates specialized communication paths for the Redundancy Switch Module (RSM), maintaining dedicated synchronization and status monitoring without consuming standard I/O bandwidth.

Rugged Industrial Construction
Manufactured to strict industrial standards, offering strong resistance to vibration and thermal stress, along with durable connectors for long-term reliability.

FAQs

Does this rack support I/O modules?
No. The 900RR0-0300 is exclusively designed for redundant CPU modules and the Redundancy Switch Module. Separate I/O racks (e.g., 900R12R) are required for field I/O.

Is the Redundancy Switch Module (RSM) included?
No. The rack is supplied as a standalone chassis. CPUs and the RSM must be purchased separately.

Can this be used for a single-CPU setup?
While technically possible, it is optimized for redundancy. Standard racks such as 900R08 or 900R12 are more suitable for non-redundant systems.

Is this product 100% brand new?
Yes. The Honeywell 900RR0-0300 is supplied as a 100% brand new, original factory unit in sealed Honeywell packaging.
