900A01-0102 Honeywell HC900 Control Process Unit HC900 Controller

Description

The 900A01-0102 Honeywell HC900 Control Process Unit (HC900 Controller) is an advanced hybrid loop/logic control unit with a modular design, engineered to meet control and data management needs for a wide range of process handling equipment. As a next-generation low-cost automated process control solution, it supports standalone operation or integrated control via open Ethernet and Modbus TCP protocol, enabling seamless connection with third-party HMI/SCADA software for network access. Key technical specifications include configurable control loop capacity: up to 8 loops for the C30 variant and up to 32 loops for the C50 variant, plus a total of 1920 input/output points, supported by compact 4, 8, or 12 input/output slot racks. It features multi-protocol communication support, including Ethernet, point-to-point communication, and serial Modbus RTU. For sequential control, it offers 8 setpoint programs, 2 setpoint sequences with multiple ramp/hold outputs, and 64 sequence execution steps. The controller integrates hybrid process, logic, and sequential control algorithms with data acquisition, and is configured via the Windows-based Hybrid Control Designer software tool, which enables graphical configuration, in-run mode editing without disrupting process control, and advanced monitoring for debugging. A Type 4X local operator interface reduces configuration time, while optional 1042, 559 operator panels, or HCi universal color touchscreens are available for extended functionality. Its modular design and flexible configuration make it suitable for diverse industrial applications, minimizing process interruptions, reducing startup time, and improving continuous processing performance.
