Honeywell HC900 Hybrid Controller

Honeywell HC900 Hybrid Controller — Process and Logic Control for Saudi Petrochemical and Refinery Applications

The Honeywell HC900 is a hybrid controller combining sequential logic control (PLC-style) and continuous process control (DCS-style) in a single platform. For Saudi Arabia's mid-tier process facilities — Jubail specialty chemical plants, Yanbu specialty gas production, and Dammam water treatment — the HC900 provides the functionality of a full DCS at the controller-level cost of a PLC.

Saudi Arabia's mid-market process facilities often can't justify a full distributed control system (DCS) investment but need more than a simple PLC can offer. The HC900 bridges this gap with hybrid control architecture — process engineers get PID control loops while instrumentation engineers get ladder logic for interlock and safety logic.

Key Features

Hybrid Architecture: Combines PID process control and ladder logic PLC functions in one controller — reduces system complexity and integration cost for mid-tier Saudi process facilities.

Modular I/O: Hot-swappable I/O modules for analog inputs, analog outputs, digital inputs, digital outputs, and high-speed counter inputs — flexible configuration for diverse process I/O requirements.

Hybrid Control Development Environment: Single configuration tool for both process control (function block) and sequential control (ladder logic) — reduces engineering time and eliminates integration issues between separate PLC and process controllers.

Modbus RTU/TCP Communications: Native Modbus communications for integration with SCADA systems and enterprise-level data acquisition — enables data logging and remote monitoring from Saudi Aramco control rooms.

Applications in Saudi Arabia

Jubail Specialty Chemical Plant: HC900 controls reactor temperature, pressure, and feed flow loops while managing safety interlocks — all in one controller replacing separate PLC and process controller.

Yanbu Specialty Gas Production: HC900 manages blending, compression, and filling sequences for industrial gas production — sequential control for batch processes with PID for continuous quality control parameters.
