Honeywell IOCHAS-0001S I/O Chassis (Baseplate)

The Honeywell IOCHAS-0001S is a fundamental hardware component for building I/O stations within the Experion® Process Knowledge System (PKS) C300 control platform. This non-redundant I/O chassis serves as a passive backplane and mechanical mounting structure, providing the physical and electrical foundation for installing C-series I/O modules and their associated termination assemblies.

Role in the Control System

As a passive component, the IOCHAS-0001S itself contains no active electronics. Its primary function is to provide a high-integrity interconnect between installed I/O modules and the system backplane. It distributes power and facilitates communication between the modules and the C300 controller, ensuring reliable data transfer. The chassis's design is critical for system maintainability, supporting the hot-swapping of I/O modules, which allows for module replacement without powering down the entire I/O station.

Key Features and Specifications

• Non-Redundant Design: Optimized for applications where full I/O redundancy is not required, offering a cost-effective and compact solution.

• Module Capacity: Provides 8 standard slots for mixing various C-series I/O module types (analog input/output, digital input/output, etc.) .

• Robust Construction: Built with high-reliability materials and features gold-plated backplane connectors designed to withstand numerous hot-swapping cycles.

• Environmental Resistance: Rated for an operating temperature range of -40°C to +70°C, making it suitable for a wide variety of industrial environments.

• Compact Form Factor: Designed for space-efficient installation in standard 19-inch control cabinets.

• Power Supply: Operates on 24 VDC power supplied to the backplane.

Technical Specifications

Integration and Compatibility

The IOCHAS-0001S is specifically designed for use with Honeywell's C300 controller and C-series I/O modules. It works in conjunction with termination bases (like TC-TBCH) that mount on the front or rear, providing the field wiring terminals. This modular approach simplifies installation, wiring, and maintenance. The chassis supports mixed I/O types, allowing users to populate the 8 slots according to the specific signal requirements of their application.

Typical Applications

This chassis is a versatile building block for various industrial control applications:

• Remote I/O Stations in Oil and Gas Pipelines

• Process Control Units in Chemical and Refining Plants

• Machine Control in Manufacturing

• Data Acquisition in Power and Water Treatment Facilities
