Unified Control Logic: The C70 processor executes PID loops and Boolean logic simultaneously. This eliminates the need for separate controllers for analog and digital tasks, simplifying your system architecture and reducing synchronization latency.
Data Security in Power Loss: The module utilizes non-volatile flash memory to store the application program. This prevents program corruption and ensures the controller resumes its precise state immediately following a power restoration, protecting your process from unmanaged restarts.
Scalable Distributed I/O: The 900C70-0360-00 manages extensive I/O counts across multiple remote and local racks. This allows engineers to expand plant capacity by adding I/O modules without upgrading the core processor, preserving your initial hardware investment.
Industrial-Grade EMI Shielding: Designed for harsh environments, the module features robust galvanic isolation. This hardware protection blocks electrical noise and transients from the factory floor, ensuring the CPU maintains stable operation near high-voltage motor starters and variable frequency drives.
Does the 900C70-0360-00 require a specific power supply?
The module draws its 5VDC logic power from the rack backplane, which is powered by a Honeywell 900P02 or 900G01 power supply module. Ensure your rack power budget supports the C70's processing load.
Which software is used to program this CPU?
You must use Honeywell HC Designer software. The software allows for graphical drag-and-drop configuration of control loops and logic sequences.
Can I use this C70 module to replace a C50 or C30 module?
While the C70 is backward compatible with most HC900 I/O modules, you must verify your existing rack firmware and software project configuration. The C70 offers higher processing capacity and I/O limits compared to the C30/C50 models.
What is the guarantee of originality?
We guarantee this product is 100% Brand New and Original. It ships in the factory-sealed Honeywell box and includes our standard 12-month professional warranty.
