Description
Foxboro FBM207C
- Technical Specifications:
- Channels: 16 isolated digital inputs
- Input Voltage: 48 V DC contact sense
- Isolation: Channel-to-channel and channel-to-ground isolation (optical isolation)
- Communication: 2 Mbps module fieldbus to FCM/FCP
- Power: 24 V DC; power dissipation under 4 W
- Environment: Operating temperature 0 °C to 60 °C; humidity within I/A Series limits
- Dimensions: Module approx. 10.4 cm × 4.5 cm × 11.4 cm; weight approx. 0.284 kg
- Functional Features:
- High-voltage digital input sensing (48 ) with isolation
- Event recording and sequence-of-events (SOE) capability
- Configurable input filter times for debouncing and noise immunity
- Supports redundant configurations for critical applications
- Application Scasts:
- Monitoring 48 V DC field devices in substations, switchgear, and control panels
- Digital input for high-voltage control circuits and equipment
- Process applications requiring higher voltage digital input levels
- Performance Parameters:
- Fast detection of input state changes with configurable filtering
- High reliability in high-voltage industrial environments
- Material and Structural Characteristics:
- Housing: Rugged industrial enclosure (aluminum or similar)
- Terminals: High-density terminal blocks for field wiring
- Connectors: Industrial connectors for fieldbus and backplane
- Working Principle:
- Each input channel senses the presence or absence of 48 V DC, using opto-isolation to separate the field circuit from the module logic, then transmits state information over the fieldbus.
- Installation Requirements:
- Mount the module on a compatible baseplate designed for I/A Series modules
- Connect field devices to the terminal block; ensure correct voltage levels and ratings
- Configure filter times and diagnostic options via engineering tools
- Usage Notes:
- Ensure field devices are rated for 48 V DC
- Verify isolation and grounding requirements are met
- Perform periodic verification of input response and channel status
