Honeywell Experion Series 8 C300 Controller Delivers Advanced Control for Modern Industrial Automation

Feb 25, 2026

The Honeywell Experion Series 8 C300 controller serves as the powerful core of the Experion distributed control system, executing deterministic control strategies and batch operations with exceptional reliability. This compact controller integrates all control execution and communications within a single module, eliminating the need for additional interface or communication modules commonly required by competing systems. The controller runs the field-proven Control Execution Environment, which provides robust and powerful control capabilities for complex industrial processes. Control strategies are easily configured and loaded through the intuitive Control Builder engineering tool, streamlining the engineering workflow. The Series 8 form factor features an innovative design that combines an Input Output Termination Assembly with an electronics module that mounts directly onto the IOTA. This passive IOTA contains only essential components such as FTE address switches and cable connectors, ensuring that all active intelligence resides in the controller module itself. The C300 controller supports both non-redundant and redundant configurations, with redundant operation achieved by adding a second identical controller with its own IOTA and a simple redundancy cable connection.

Innovative Series 8 Design Enhances Heat Management and Reduces Footprint

The Series 8 platform introduces groundbreaking design elements that significantly improve heat management while reducing overall system footprint compared to previous generations and competitor offerings. The tilted design of Series 8 components facilitates effective heat dissipation within cabinet enclosures, which is critical for maintaining high system availability when cabinet density increases. Vertical mounting orientation enables more efficient wiring since most field wiring applications require entry from the top or bottom of systems cabinets. An innovative information circle provides maintenance technicians with immediate visual cues directing attention to important status information, simplifying troubleshooting and routine maintenance tasks. Both Series 8 I/O modules and IOTAs are available with conformal coating options, providing enhanced protection against moisture, dust, chemicals, and temperature extremes for installations in harsh environments. The unique styling represents a significant advancement in control hardware design, combining functional excellence with practical features that support effective use in real-world systems environments.

 

Integrated IOTA Architecture Simplifies Installation and Reduces Costs

The Series 8 IOTA architecture consolidates multiple functions into a single equipment assembly, dramatically simplifying installation and reducing total installed costs. Field terminations combine with I/O modules in the same physical area, eliminating the need for separate chassis to hold electronics assemblies. Two-level detachable terminals facilitate easier plant installation and maintenance by allowing field wiring to be landed and later removed without disturbing connections. Field power distributes directly through the IOTA without requiring external marshalling or additional power supplies, representing significant material and labor savings. Redundancy is achieved directly on the IOTA by simply adding a second I/O module, requiring no external cabling or separate redundancy control devices. Input and output circuits include built-in short circuit protection, eliminating the need for in-line fusing and further reducing installation and maintenance costs. The modular connector design for field connections allows removal and insertion of field wiring, significantly streamlining installation procedures and assisting during field checkout activities.

 

Comprehensive I/O Offering Supports Scalable System Configurations

The C300 controller supports a comprehensive range of Series 8 I/O modules through redundant IO Link interfaces that provide reliable connections between the controller and associated I/O modules. Analog modules typically provide sixteen points and reside on six-inch IOTAs for non-redundant applications or twelve-inch IOTAs when redundancy is required. Discrete modules offer thirty-two points and mount on nine-inch IOTAs for standard configurations or twelve-inch IOTAs for redundant operation. The modular architecture allows users to right-size their systems based on specific application requirements while maintaining the flexibility to expand or upgrade as needs evolve. IOTA sizing follows nominal dimensions of six, nine, or twelve inches corresponding to 152, 228, and 304 millimeters respectively, providing standardized mounting arrangements that simplify cabinet layout and design. The combination of flexible I/O options, scalable redundancy configurations, and compact footprint enables the Experion Series 8 C300 controller to deliver useful, maintainable process equipment connections while occupying significantly less space than equivalent products from competitors. This space efficiency contributes directly to lower overall total installed costs while maintaining the robust performance and reliability expected from Honeywell's Experion control platform.
