Product Overview

Belden AF100 9688 0101000 Replacement for AF100 Series: Seamless Transition & Legacy System Compatibility

When your existing control system relies on Belden AF100 series shielded control cables and the original AF100 9688 0101000 reaches end-of-life or becomes difficult to source, a carefully planned cable replacement strategy is essential to maintaining system integrity. The Belden AF100 9688 0101000 is a multi-conductor shielded control cable engineered for demanding industrial environments — commonly deployed in PLC panel wiring, DCS field instrument loops, motor drive signal circuits, and distributed I/O interconnections. Its foil-and-braid shielding architecture provides robust EMI/RFI rejection, making it a preferred choice in noise-sensitive automation environments where signal fidelity directly impacts process control accuracy.

Upgrading or replacing this cable within an existing control cabinet does not require a full system redesign. The AF100 9688 0101000 maintains standard conductor sizing, color coding, and drain wire configuration consistent with the broader AF100 series family, allowing direct substitution in most retrofit scenarios without rewiring terminal blocks or modifying cable trays. Engineers migrating from older Belden catalog numbers within the same series — such as the 9688 or adjacent multi-pair variants — will find that conductor cross-sections, insulation ratings, and jacket materials remain compatible with existing cable glands, conduit entries, and DIN rail-mounted terminal strips already installed in the field.

Seamless Upgrade Solutions

A successful cable replacement within an active control system rarely involves the cable alone. During a typical AF100 9688 0101000 retrofit, engineers commonly address the full signal path from field device to controller. At the field end, instruments such as pressure transmitters, flow meters, and temperature sensors connect through cable glands and junction boxes before signals travel through the shielded cable run to the marshalling cabinet. Within the cabinet, signals terminate on Phoenix Contact or Weidmüller DIN rail terminal blocks before routing to Siemens S7-300 or S7-400 analog input modules — or equivalent Rockwell Automation 1756 ControlLogix I/O modules — depending on the plant’s control platform.

Where the existing cable run passes through areas with elevated electromagnetic interference — near variable frequency drives (VFDs), servo amplifiers, or high-current bus bars — engineers often install signal isolators or Pepperl+Fuchs galvanic isolators in series with the cable circuit to maintain signal integrity after the cable swap. In DCS environments built on Honeywell Experion or Yokogawa CENTUM VP platforms, the AF100 9688 0101000 is frequently used for field instrument loops connecting to remote I/O cabinets, where Yokogawa AAI141 or equivalent analog input cards receive the 4–20 mA signals.

For systems where the cable replacement coincides with a broader control panel upgrade, the opportunity to standardize on Belden’s current AF100 series catalog simplifies future spare parts management. Pairing the AF100 9688 0101000 with Belden’s complementary DeviceBus or Profibus cables for the same panel ensures consistent shielding philosophy and jacket compatibility across all cable types in the enclosure. Where fiber optic communication backbones are present — such as Profinet or EtherNet/IP rings connecting remote I/O drops — the copper control cable replacement does not affect the fiber infrastructure, allowing the two upgrade activities to proceed independently without system-wide downtime.

In retrofit projects involving older Allen-Bradley PLC-5 or SLC 500 systems migrating to CompactLogix or ControlLogix platforms, the AF100 9688 0101000 is often retained as-is for field wiring while only the I/O modules and backplane are replaced — a cost-effective approach that avoids full cable tray replacement and significantly reduces installation labor. Similarly, in Mitsubishi MELSEC Q-series or iQ-R series panel upgrades, existing shielded control cable runs are preserved and re-terminated at new I/O module terminal connectors, with the AF100 9688 0101000’s drain wire grounded at the panel end per IEC 61000-5-2 shielding best practices.

Retrofit Guidance FAQ

Q: Can I replace the AF100 9688 0101000 without rewiring terminal blocks?
A: Yes. The conductor sizing and color coding of the AF100 9688 0101000 are consistent with the AF100 series standard, allowing direct re-termination at existing terminal blocks without label changes in most installations.

Q: Is the shield grounding method compatible with my existing panel?
A: The AF100 9688 0101000 uses a foil shield with drain wire, which is compatible with standard single-end grounding practice at the control panel. No additional grounding hardware is required if your existing cable glands and shield clamps are already installed.

Q: Will this cable work with both analog 4–20 mA and discrete I/O circuits?
A: Yes. The cable is suitable for both analog instrument loops and discrete control signal wiring, making it versatile across mixed I/O panel layouts.

Q: Does the cable fit existing conduit and cable tray installations?
A: The AF100 9688 0101000 maintains the same outer diameter as equivalent AF100 series cables, ensuring compatibility with existing conduit fill calculations and cable tray capacity without requiring physical modifications.

Q: What communication protocols does this cable support?
A: This shielded control cable supports analog signal transmission (4–20 mA, 0–10 V), discrete I/O, and low-speed serial communication circuits. It is not designed for high-speed fieldbus protocols such as Profibus DP or EtherNet/IP, which require dedicated bus cables.

Q: How do I handle the transition period when replacing cable in a live system?
A: Plan the cable pull during a scheduled maintenance window. Pre-cut and label replacement cable sections before the outage. Use the existing cable as a pull wire where conduit routing permits. Re-terminate and test each circuit individually before restoring power to minimize troubleshooting time.
