Description
Foxboro P0916BX
- Technical Specifications
- Type: Compression Termination Assembly (CTA) / Terminal Module
- Compatible FBM Modules: FBM214, FBM261, and other I/A Series modules that use P0916BX as their designated termination
- Terminal Type: Screw terminals for secure field wiring
- Voltage Rating: Supports low-voltage I/O signals typical of I/A Series (e.g., 24 V DC digital; analog signal ranges per associated )
- Current Rating: Compatible with per-channel current limits of the associated FBM
- Environmental Operating Temperature: 0 °C to 60 °C (per I/A Series environment; some sources list -20 °C to +70 °C for harsh variants)
- Storage Temperature: -40 °C to +85 °C
- Relative Humidity: 5% to 95% non-condensing
- Materials: Insulating body (plastic/compression nylon; PVC in some listings), metal contacts and hardware
- Protection: Provides isolation and grouping consistent with I/A Series electrical safety standards (creepage/clearance per module ratings)
- Certification/Compliance: Designed for industrial control panels; conforms to applicable IEC low-voltage directives when used as part of a Foxboro I/A system
- Functional Features
- Provides pre-engineered termination points for field device wiring, reducing wiring complexity
- Supports hot-swap of modules in redundant or non-redundant configurations by allowing field wiring to remain terminated on the assembly while the module is replaced
- Compression termination design ensures stable contact and resistance to vibration
- Clear labeling and modular layout facilitate maintenance and troubleshooting
- Application Scenarios
- Marshalling cabinets where field sensors and actuators are wired into Foxboro I/A Series I/O
- Process industries including oil and gas, chemical, power generation, and water treatment
- Environments requiring high reliability and maintainability of field wiring connections
- Performance Parameters
- Maintains signal integrity for both analog and digital I/O channels
- Low contact resistance and robust termination ensure stable measurements and actuation
- Supports I/O scanning rates and diagnostic coverage of the associated FBM modules
- Material and Structural Characteristics
- Housing: High-quality insulating plastic (e.g., polyvinyl chloride (PVC) and compression nylon (PA)) to withstand industrial environments
- Contacts and screws: Metal (typically copper alloy with plating) for reliable conductivity and corrosion resistance
- Structural design includes keyed or keyed-connector features to ensure correct alignment with the module
- Compact footprint suitable for dense cabinet layouts
- Working Principle
- The termination assembly provides the physical and electrical interface between the FBM module and field cables. Each terminal point corresponds to a channel on the, routing signals (voltage, current, digital states) to and from the field devices while maintaining isolation and protection per module design.
- Installation Requirements
- Mount in an enclosure or cabinet in close proximity to the FBM modules
- Connect field wires to screw terminals per I/A Series wiring diagrams, ensuring correct torque and wire gauge
- Secure the assembly to prevent movement or vibration from loosening connections
- Ensure proper grounding of the assembly and cabinet as per system standards
- Usage Notes
- Use only specified wire gauges and terminal tightening torque to avoid damage
- Periodically inspect terminal tightness and signs of corrosion or overheating
- Replace only with the same P0916BX part number to maintain compatibility and safety ratings
- Follow local electrical codes and Foxboro installation guidelines for grounding and shielding
