Description
Foxboro FBM07
Technical Specifications
- Model Number: FBM07
- Input Type: Dry Contact / DC Voltage
- Channels: 16 Discrete Inputs
- System Compatibility: Foxboro I/A Series
Functional Features
- Versatile Input: Accepts both mechanical switch closures and solid-state DC voltage signals.
- Debouncing: Hardware and software debouncing prevents false triggering from mechanical switch bounce.
- High Density: 16 channels per module maximize panel space utilization.
Application Scenarios
Used extensively in motor control centers (MCCs), conveyor systems, and safety interlock panels to monitor equipment status.
Performance Parameters
- Scan Rate: Fast enough to capture transient events and rapid state changes.
- Noise Immunity: Excellent rejection of electrical noise typical in motor environments.
Material Composition
Ruggedized PCB with opto-isolators for each channel to protect the fieldbus from field-side transients.
Structural Characteristics
- Standard FBM Form Factor: Plugs into standard I/A Series baseplates.
- Terminal Block: Spring-clamp or screw-terminal options for secure field wiring.
Working Principle
Field contacts close a circuit to an internal reference voltage. Opto-isolators convert this to a digital signal, which is scanned by the onboard microprocessor and transmitted over the fieldbus.
Installation Requirements
Use shielded cables for long wire runs. Ensure the common return path is properly grounded at the module.
Usage Precautions
Verify the voltage rating of the discrete inputs. Do not connect AC voltage to DC-rated input channels.
