Description
Foxboro FBM207B
Technical Specifications
- Model Number: FBM207B (Part Number: P0914WH)
- Channel Capacity: 16 discrete input channels
- Signal Type: 24 VDC Contacts / Voltage
- Optional Redundancy: Supports redundant configurations
Functional Features
- High Density: 16 channels per module maximize panel space utilization.
- Fast Scanning: Optimized for high-speed sequential control and safety interlocks.
- Diagnostic Feedback: Reports wire breaks and channel faults to the host controller.
Application Scenarios
Used extensively in motor control centers (MCCs), conveyor systems, and safety interlock panels to monitor equipment status.
Performance Parameters
- Scan Rate: Deterministic and fast enough for critical safety logic.
- Noise Immunity: High rejection of common-mode and differential-mode electrical noise.
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.
- Visual Indicators: LEDs for power, bus communication, and channel status.
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 DC voltage rating of the discrete inputs. Do not connect AC voltage to this DC-rated module.
