Description
Product Name: 1797-BIC Allen Bradley Power module
Product details:
The Allen-Bradley 1797-BIC is a critical component of the FLEX Ex I/O system, which allows for the installation of control systems in hazardous locations classified as Zone 1 or Zone 2. Its primary function is to provide an intrinsically safe barrier and communication link between the standard control environment and the hazardous field devices.
Product Details & Specifications (Product Parameters)
| Feature | Detail |
| Product Type | FLEX Ex Bus Isolator Module |
| Catalog Number | 1797-BIC |
| Function | Provides intrinsic safety isolation and establishes the communication path (FLEX Ex Bus) between the non-hazardous area (safe area) and the intrinsically safe field devices in the hazardous area. |
| Compatibility | Used with the Allen-Bradley 1797 FLEX Ex I/O System. |
| Hazardous Area | Designed for use in Zone 1 or Zone 2 hazardous locations (depending on the specific system configuration and certifications). |
| Mounting | Typically mounts onto a backplane or carrier within the FLEX Ex system. |
| Dimensions (Approx.) | 87 x 94 x 75 mm (3.4 x 3.7 x 3.0 in) |
| Weight (Approx.) | 0.2 kg (0.4 lb) |
(Note: Specific certifications, operating temperature, and voltage ratings should always be confirmed using the official Rockwell Automation data sheet for guaranteed accuracy in a deployed system.)
Product Advantages (Product Advantages)
- Intrinsic Safety: Provides a certified barrier to limit energy transferred to the hazardous area, preventing ignition of explosive atmospheres (gases, vapors, or dust). This is its core benefit.
- Modular Design (FLEX Ex): Allows for a flexible, distributed control architecture, enabling I/O to be placed close to field devices in hazardous areas.
- Hot Swappable: In many FLEX Ex configurations, modules are designed to be replaceable while the system is running, minimizing downtime.
- Simplified Wiring: Integrates the power and communication bus for the intrinsically safe I/O modules, streamlining installation.
- Diagnostics: Often provides status indicators and diagnostics to aid in troubleshooting the communication link and power status.
Important Considerations (Notes/Precautions)
- Certification Compliance: Crucially, the entire system (including the 1797-BIC, power supply, and I/O modules) must be installed and wired strictly according to the relevant Intrinsically Safe documentation and area classification codes (e.g., ATEX, IECEx, UL). Failure to do so invalidates the safety rating.
- System Integrity: Only compatible 1797-Ex I/O modules can be connected downstream of the 1797-BIC. Mixing safe and non-safe components incorrectly will compromise safety.
- Documentation: Always refer to the official Allen-Bradley/Rockwell Automation installation and user manual for detailed wiring diagrams, grounding requirements, and maximum cable lengths.
- Grounding: Proper grounding of the system is essential for maintaining the intrinsic safety and EMI/RFI immunity.
Product Applications (Product Applications)
The 1797-BIC is primarily used in industries where control and monitoring equipment must operate in environments with the potential for explosion:
- Oil and Gas: Monitoring and control of pipelines, wellheads, refineries, and offshore platforms.
- Chemical and Petrochemical: Process control in plants dealing with flammable liquids and gases.
- Pharmaceutical: Control systems in areas where solvents or flammable powders are handled.
- Grain Processing & Silos: Monitoring systems in areas where combustible dust is a hazard.
- Wastewater Treatment: Control systems near digesters or other sources of flammable gases.
