Description
Foxboro FBM10
Technical Specifications
- Model Number: FBM10
- Input Type: 120 VAC Status
- Output Type: Contact (2A rating)
- Configuration: 8 AC Inputs / 8 Relay Outputs
Functional Features
- Direct AC Interface: Safely reads 120VAC signals without external transformers.
- High-Power Outputs: Relay contacts rated for 2A, capable of driving solenoids and contactors directly.
- Optical Isolation: Protects the low-voltage fieldbus from high-voltage AC transients.
Application Scenarios
Widely used in legacy plant upgrades, motor control panels, and facilities where 120VAC is the standard control voltage.
Performance Parameters
- Dielectric Strength: High isolation rating between AC field circuits and the control bus.
- Relay Endurance: Mechanical relays rated for millions of operations.
Material Composition
Heavy-duty AC input resistors and high-capacity relay contacts enclosed in a flame-retardant housing.
Structural Characteristics
- Safety Design: Physical barriers between high-voltage and low-voltage sections.
- Clear Markings: High-voltage warning labels and distinct terminal coloring.
Working Principle
AC input signals are rectified and opto-isolated before being processed as digital states. Output commands energize relay coils, closing contacts to switch the 120VAC load.
Installation Requirements
Strictly adhere to high-voltage wiring practices. Ensure the panel is properly grounded and locked out during installation.
Usage Precautions
Only qualified electricians should wire this module. Never exceed the 2A output contact rating. Verify AC frequency compatibility.
