The Honeywell HC900 Hybrid Controller is an advanced loop and logic controller offering a modular design sized to satisfy the control and data acquisition needs of a wide range of process equipment.
The HC900 Hybrid Controller provides advanced PID loop control and robust analog processing in a compact, rack‑mountable design. It supports up to 32 PID loops, 960 total I/O points (including 256 isolated analog inputs) and offers flexible remote I/O racks that can be installed up to 300 m away.
Configuration is performed with the Windows‑based Hybrid Control Designer software over Ethernet, RS‑232 or modem connections. The controller includes a rich library of more than 100 function blocks, fast‑scan logic (27 ms), and open 10 MB Ethernet using Modbus/TCP, enabling integration with HMI/SCADA systems and peer‑to‑peer communication.
