Honeywell 900C72-0144-00 HC900 C70 Hybrid Controller CPU Unit

Feature & Principle

This hybrid controller integrates continuous process PID control and sequential logic function. It collects field I/O signals through backplane bus, runs control programs, and exchanges data with HMI and upper DCS via Ethernet. It supports redundant configuration, built-in fault diagnosis, and can realize stable closed-loop control of temperature, pressure and flow.
