Description
Product Name: 2771P-T15C4D8 Allen Bradley Controller module
Product details:
The 2760-SFC2 is a protocol cartridge designed to be inserted into the Allen-Bradley 2760-RB Flexible Interface Module (part of the older PLC-5 architecture) to enable specific communication protocols.
📝 Product Parameters (Specifications)
Since the 2760-SFC2 is a cartridge, its physical specifications are minimal, and its operational parameters are tied to the 2760-RB Flexible Interface Module and the protocol it enables.
| Parameter | Detail | Note |
| Product Type | Protocol Cartridge | Inserts into the 2760-RB module. |
| Associated Module | Allen-Bradley 2760-RB Flexible Interface Module | Required host module. |
| Target Platform | Allen-Bradley PLC-5 System | Used in the legacy PLC-5 racks. |
| Function | Defines Communication Protocol | It enables the 2760-RB module to communicate using a specific protocol. |
| Typical Protocol Enabled | DH-485 (Data Highway 485) | A common use for the 2760-SFC2 mentioned in relation to connecting devices like AdaptaScan Barcode Readers. |
Note on 2760-RB Specifications (The host module):
- Slots: Typically occupies two slots in a 1771 I/O rack.
- Input Voltage: 5 Volts DC
- Input Current: 1.28 Amps
- Configuration: DIP Switches on the module.
➕ Product Advantages (Benefits)
- Protocol Flexibility: It allows a single 2760-RB hardware module to be adapted to different communication needs by simply swapping the cartridge (e.g., from an SFC1 to an SFC2).
- Legacy Device Integration: Specifically enables the 2760-RB to interface with devices that use protocols like DH-485, such as barcode readers (e.g., AdaptaScan), extending the life and capability of existing PLC-5 systems.
- Dedicated Communication: Provides a dedicated channel for point-to-point or network communication, offloading the main PLC processor.
⚠️ Important Considerations (Precautions/Notes)
- Obsolete/Legacy Status: The PLC-5 platform and its associated modules (including the 2760-RB and 2760-SFC2) are obsolete (Discontinued by the manufacturer, Rockwell Automation). While they are still in use, spare parts and support are becoming increasingly difficult to find.
- Requires Host Module: The cartridge is useless without the functioning 2760-RB Flexible Interface Module.
- Specific Protocol: Ensure the 2760-SFC2 cartridge enables the exact protocol required for the connected device (e.g., DH-485 for specific devices). Other cartridges, like the 2760-SFC1, enable different protocols.
- Migration Planning: Due to the obsolete status, users should have a long-term plan for migrating their PLC-5 systems to modern platforms like the Allen-Bradley ControlLogix or CompactLogix series.
🏭 Product Applications
The 2760-SFC2, via the 2760-RB module, is used in industrial control systems running the PLC-5 platform to manage specialized communication tasks.
- Barcode Reader Integration: Connecting devices like the AdaptaScan barcode reader to the PLC-5 over the DH-485 protocol for tracking products in manufacturing or logistics.
- Specialized Device Interfacing: Communicating with other proprietary or specialized equipment that uses the specific protocol enabled by the SFC2 cartridge (often DH-485).
- Legacy System Expansion: Adding new communication capabilities to an existing, operational PLC-5 system without having to upgrade the entire control architecture.
