Description

The Foxboro FBM242 (P0916TA) is a high-density Discrete Output Interface Module designed for the I/A Series Distributed Control System (DCS). This module features 16 discrete output channels specifically engineered to interface with external termination assemblies for switching field loads. Commonly deployed in heavy industrial environments such as power generation plants, petrochemical refineries, and mining facilities, the FBM242 acts as the primary control interface for solenoids, motor starters, and indicator lamps. Its robust hardware design provides critical isolation between the internal control logic and field circuitry. By facilitating reliable signal execution and supporting redundant communication via the Fieldbus, the FBM242 ensures high system availability and minimizes process interruptions.

Features

• 16-channel discrete output interface for high-density control requirements.
• Redundant 2 Mbps Fieldbus communication for high system availability.
• Optical isolation (1500 VAC) between field-side circuitry and internal logic.
• Integrated self-diagnostics for continuous health monitoring and fault reporting.
• Designed for use with External Termination Assemblies (ETAs) for flexible field wiring.

Applications

The FBM242 is suitable for critical industrial control applications including:

• Solenoid valve control in process automation.
• Motor starter and contactor switching.
• Indicator lamp and alarm signaling.
• General-purpose discrete output logic for DCS-based control loops.
