Where This Product Is Used
The Allen-Bradley 1747-KFC15 is a serial communication interface module designed for SLC 500 fixed and modular chassis systems. It is widely deployed in the following industrial environments:
- Automotive assembly lines — point-to-point DF1 communication between PLCs and SCADA hosts
- Food & beverage processing plants — DH-485 multi-drop networks linking SLC 500 controllers to HMI panels (PanelView series)
- Water & wastewater treatment facilities — remote monitoring via RS-232/RS-485 serial links to RTUs
- Pharmaceutical manufacturing — validated serial communication paths in 21 CFR Part 11 environments
- Material handling & conveyor systems — coordinating multiple SLC 500 nodes on a DH-485 token-passing network
- OEM machine builders — embedded serial gateway between SLC 500 and third-party devices (drives, barcode readers, weighing systems)
- Building automation & HVAC — legacy integration of SLC 500 controllers with BMS systems via DF1 protocol

Why Engineers Specify This Model
- Dual-protocol flexibility: Supports both DF1 (RS-232) and DH-485 simultaneously, eliminating the need for external converters in mixed-network architectures.
- Proven SLC 500 ecosystem fit: Native backplane integration — no external power supply or gateway hardware required.
- RSLinx & RSLogix 500 compatibility: Fully configurable through standard Rockwell software toolchain, reducing commissioning time.
- Long-term availability: Critical spare for installed SLC 500 base; widely stocked for MRO and emergency replacement scenarios.
- Deterministic token-passing on DH-485: Ensures predictable scan times in multi-node HMI/PLC networks.
- Compact single-slot form factor: Preserves chassis slots in space-constrained panels.

Application-Specific FAQ
Q: Can the 1747-KFC15 replace a 1747-KE or 1747-KFC module?
A: The KFC15 is the enhanced revision of the KFC series. It is backward-compatible with most SLC 500 applications using DF1 or DH-485. Verify firmware revision requirements in your RSLogix 500 project before substitution.
Q: Does this module support EtherNet/IP or DeviceNet?
A: No. The 1747-KFC15 is a serial-only module (RS-232/RS-485). For EtherNet/IP connectivity, consider the 1747-AENTR or 1756-ENBT (ControlLogix). For DeviceNet, use the 1747-SDN scanner module.
Q: How many HMI panels can be connected on DH-485?
A: DH-485 supports up to 32 nodes. In practice, 8–16 nodes is typical for reliable performance at 19.2 Kbps. Each PanelView terminal counts as one node.
Q: Is RSLinx Classic required for configuration?
A: RSLinx Classic (or RSLinx Enterprise) is required to configure the driver and establish communication. RSLogix 500 is used for ladder logic programming. Both are Rockwell Automation software products.
Q: What is the warranty on this part?
A: Konmask.com provides a 90-day functional warranty on all tested units. Extended warranty and exchange programs are available — contact us for details.
Q: Can you supply a Certificate of Conformance (CoC)?
A: Yes. CoC and inspection reports are available upon request for quality-critical procurement processes.
