Description

The Foxboro FBM242 (P0916TA) is a high-density discrete output interface module designed for the I/A Series distributed control system. This module provides 16 isolated digital output channels, enabling the reliable switching of external field loads such as solenoid valves, motor starters, and pilot lights. Engineered for demanding industrial environments including petrochemical refineries, power generation, and pulp and paper processing, the FBM242 ensures deterministic execution of binary control logic. It features individual channel-to-ground isolation and supports redundant communication paths to protect the control network from field-side electrical interference.

Features

• High-Density Design: 16 sourcing output channels in a compact Eurocard form factor.
• Redundant Communication: Dual-redundant Fieldbus interfaces for continuous connectivity with the Control Processor.
• Solid-State Reliability: Utilizes solid-state switching to eliminate mechanical fatigue common in traditional relay modules.
• Integrated Protection: Built-in suppression circuitry manages back-EMF from inductive loads.
• Diagnostic Indicators: Onboard LED indicators provide real-time status for each output channel to facilitate field diagnostics.
• Hot-Swappable: Supports replacement while the baseplate is powered, minimizing process downtime.

Applications

The FBM242 is suitable for critical control applications requiring high-density discrete outputs, including:

• Process control and automation in refineries.
• Solenoid valve and motor starter control.
• Safety-related binary logic execution.
• Harsh industrial environments requiring ISA S71.04 G3 compliance.

Technical Specifications

Installation Guidelines

• Mounting: Designed for installation into standard Foxboro I/A Series high-density baseplates.
• Handling: Use proper ESD protection when handling the module to prevent damage to sensitive internal components.
• Wiring: Ensure all field wiring is properly shielded and routed away from high-EMI sources to maintain signal integrity.
• Power: While the module is hot-swappable, ensure the baseplate power is stable before insertion. Verify that the output voltage range matches the field load requirements.
• Grounding: Maintain proper chassis grounding of the baseplate to ensure effective galvanic isolation.

FAQ

Is the FBM242 hot-swappable?
Yes, the FBM242 is designed to be hot-swappable, allowing for replacement without powering down the entire baseplate or affecting adjacent modules.

What does the P0916TA designation mean?
P0916TA is the specific order code for this version of the FBM242 module within the Foxboro I/A Series ecosystem.

Does this module require external power for the outputs?
Yes, the module provides sourcing outputs that require an external DC power supply within the 15 to 60 VDC range to drive the field loads.
