Overview
The Honeywell 900C70-0360-00 C70 CPU actively manages process automation tasks for HC900 Controller systems. It supports up to 1920 I/O points and executes advanced function block programming with scan times as fast as 27 ms. Moreover, the modular design allows system expansion through 4-, 8-, or 12-slot racks, providing engineers flexible integration options. Dual Ethernet and RS-485/RS-232 interfaces enable high-speed data exchange via Modbus/TCP, OPC, and Peer-to-Peer protocols. Therefore, this CPU is ideal for both local and distributed control environments.
Key Benefits
