Description

The Foxboro FBM219 (P0916RH) is a high-density combined discrete input/output module engineered for the I/A Series Distributed Control System (DCS). It features 24 discrete input channels and 8 discrete output channels, providing a versatile solution for monitoring and controlling industrial equipment. This module is widely implemented in power generation, chemical processing, and mining operations to manage motor starters, solenoids, and status indicators. By consolidating both input and output functions into a single hardware unit, the FBM219 optimizes cabinet space and reduces system complexity. Its robust design facilitates high-speed signal processing and galvanic isolation, which are critical for protecting the control network from field-side electrical interference and ensuring continuous process availability.

Features

• High-Density I/O: 24 discrete input channels and 8 discrete output channels in a single module.
• Galvanic Isolation: 1500 VAC isolation between field wiring and internal system logic to prevent interference.
• Redundant Communication: Interfaces with the redundant 2 Mbps I/A Series Fieldbus for high availability.
• Configurable Filtering: Supports software-configurable digital filtering for inputs to mitigate contact bounce.
• Fail-Safe Logic: Outputs support predefined fail-safe states upon loss of communication.

Applications

The FBM219 is designed for critical process control environments, including:

• Motor control and starter management.
• Solenoid valve actuation and monitoring.
• Status indication and alarm monitoring.
• General-purpose discrete signal processing in DCS architectures.

Technical Specifications

Installation Guidelines

• ESD Precautions: Always use a grounded wrist strap when handling the module to prevent electrostatic discharge damage.
• Baseplate Mounting: Ensure the module is fully seated into the designated I/A Series baseplate slot before securing.
• Power Status: Ensure the system power is off or the module is hot-swappable compliant (per specific I/A Series revision) before insertion or removal.
• Wiring: Use shielded cabling for field connections to minimize EMI/RFI interference. Ensure proper grounding of cable shields at the cabinet entry point.
• Environment: Maintain adequate ventilation within the control cabinet to stay within the 0 to 60 deg C operating range.

Compliance and Certifications

The FBM219 module is designed to meet international standards for industrial control equipment, including CE marking, CSA certification, and FM Approval for Class 1, Division 2 hazardous locations.

FAQ

Is the FBM219 compatible with older I/A Series systems?

The FBM219 is designed for I/A Series DCS environments. Compatibility depends on the specific software revision and baseplate type; please verify your system's hardware compatibility list (HCL) before installation.

Does this module support hot-swapping?

Yes, the FBM219 is designed for hot-swapping within the I/A Series rack architecture, allowing for module replacement without shutting down the entire control processor.
