Product Overview
The Honeywell 900C75-0560 represents the high-availability core of the ControlEdge HC900 Hybrid Control System. This C75 redundant controller CPU manages complex logic and process control loops with a typical scan time of just 25 milliseconds. It provides the essential processing power for demanding industrial environments, supporting up to 4,000 I/O points and offering 10 MB of user memory. By utilizing a dual-redundant architecture, the 900C75-0560 eliminates downtime by ensuring an instantaneous, bumpless failover if the primary processor encounters a fault.

Engineering Advantages
-
Bumpless Failover Technology: In a redundant pair, the 900C75-0560 synchronizes data across both CPUs every scan cycle. If the primary unit fails, the backup unit assumes control without dropping a single process variable, protecting volatile chemical or thermal processes from interruption.
-
Massive Scalability: While compact, this CPU manages up to 4,000 I/O points. It allows engineers to start with small-scale automation and expand the system by adding I/O racks without upgrading the central processing hardware.
-
Multi-Protocol Communication: Integrated dual Ethernet ports support Modbus TCP/IP and Ethernet/IP simultaneously. This allows the 900C75-0560 to communicate with HMIs, third-party PLCs, and SCADA systems without requiring expensive external gateways.
-
Optimized Thermal Footprint: The module operates efficiently within a dense rack environment. Its hardware design minimizes heat generation, ensuring stable 25ms scan times even when the processor handles high-density PID loops and complex logic sequences.
FAQs
Q: Is the 900C75-0560 unit 100% Brand New or refurbished?
A: We supply only 100% Brand New, original Honeywell hardware. Each unit ships in factory-sealed packaging with original serial numbers and carries a 12-month comprehensive warranty.
Q: Can I use the 900C75-0560 in a non-redundant configuration?
A: While designed for redundancy, the C75 series functions perfectly in a single-CPU setup. However, utilizing two 900C75-0560 units in a redundant rack provides the fault tolerance required for mission-critical process safety.
Q: Does this module require a specific rack for installation?
A: Yes. The 900C75-0560 must be installed in an HC900 Redundant Power/CPU rack. This rack provides the backplane synchronization necessary for the two CPUs to exchange state data in real-time.
Q: What is the benefit of the 10 MB user memory?
A: The 10 MB memory capacity allows for extensive logic programming, large setpoint tables, and detailed historical data buffering within the CPU. This ensures you do not run out of memory when implementing complex safety or regulatory control strategies.
