Honeywell FC-IOCHAS-0001R Redundant I/O Chassis | Safety Manager

Product Description

Overview

The Honeywell FC-IOCHAS-0001R (Redundant I/O Chassis) is a robust 19-inch rack solution designed to host and interconnect redundant input/output modules within the Honeywell Safety Manager™ system. Engineered for safety-critical industrial applications, it provides seamless failover between I/O module pairs, ensuring continuous operation in emergency shutdown (ESD), fire & gas (F&G), and high-integrity process control systems.

This chassis supports fault-tolerant configurations, housing up to 9 pairs of redundant I/O modules (18 total slots) while maintaining system integrity even under module failures.

Key Features and Capabilities

Redundancy & High Availability

• Supports dual I/O modules for each slot pair, enabling automatic failover without process interruption.

• Contains 21 slots: 18 for redundant I/O modules and 2 for bus interface modules (slots 20–21).

• Odd-numbered slots controlled by Control Processor 1; even-numbered slots controlled by Control Processor 2.

Industrial-Grade Construction

• Fully compatible with Honeywell Safety Manager QMR (Quadruple Modular Redundancy) systems.

• Built for extreme environments, operational between -5°C and +70°C.

• Swing-up front cover shields cabling and simplifies module replacement and maintenance.

Electrical & Communication Integration

• Includes IOB-0001R backplane for module connections and IOBUS-HBR for horizontal bus routing.

• Efficient power distribution for both 5V DC and 24V DC to all installed modules.

• Interfaces with a wide range of Honeywell I/O modules, supporting standard industrial communication protocols.
