Product Introduction
What the S-D4030-A Does
The Reliance Electric S-D4030-A is a CC-Link communication control card used with Reliance control-system hardware. It provides the interface required to connect compatible Reliance drive/control equipment to a CC-Link network, making it a communication-layer component rather than a standalone PLC CPU or general-purpose I/O card. Available references identify it specifically as the CCLK-1 CC-Link Card.
For maintenance teams supporting older Reliance installations, the S-D4030-A is valuable because it preserves the existing network architecture. The key issue is compatibility. The card must be evaluated as part of the controller, backplane, firmware, and CC-Link configuration—not simply as an isolated communication board.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A CC-Link failure on an older drive system can look like a controller failure when the actual problem is the network option card. A node may disappear from the supervisory controller, drive commands may stop updating, or network diagnostics may show repeated communication faults. Before replacing the S-D4030-A, check the CC-Link cable, termination, station configuration, master settings, and the controller option-card configuration.
Typical Applications
- Industrial Drives — CC-Link communication between Reliance drive-control equipment and a plant control network.
- Factory Automation — Networked motor-control systems requiring cyclic data exchange.
- Material Handling — Drive coordination and supervisory control across conveyor and handling equipment.
- Legacy Motion Systems — Maintaining existing PSC-based control architectures without redesigning the complete network.
Technical Pitfalls to Avoid
- Match the option-card designation.
The documentation identifies CCLK-1 / S- as the CC-Link card and lists it as an option for the PSC7000 controller. Do not confuse it with the similarly numbered S-D4000-series I/O and synchronization cards. - Verify the controller and backplane combination.
The PSC7000 documentation lists several related option cards and backplanes, including the six-slot SSBP-2 / S-D4022 and remote-I/O backplane SSBP-1 / S-D4017. Card compatibility depends on the actual system architecture. - Do not diagnose the card before checking the CC-Link network.
Station addressing, network termination, cable integrity, master configuration, and node status should be checked first. A healthy card cannot compensate for an incorrectly configured network. - Preserve the original configuration.
For a machine-down replacement, record the existing card position, controller configuration, network station parameters, and diagnostic status before removing the failed card. This makes post-replacement verification much easier.
Related Products
- CCLK-1 / S- — The functional designation associated with the S–A. It is the closest identification when searching engineering documentation for the CC-Link option card. The documented part number is 173401.
- PSC7000 Control Card — The primary controller associated with the S- CC-Link option. The S- is an expansion communication card, while the PSC7000 provides the main control function.
- S-D4017 / SSBP-1 — Remote I/O backplane. It supports the remote-I/O portion of the Reliance architecture and is not a substitute for the S- communication card.
- S-D4022 / SSBP-2 — Six-slot backplane used with the PSC option-card architecture. It provides the physical card infrastructure rather than CC-Link communication itself.
- S-D4006 / DIO-1 — Digital I/O card. It handles discrete I/O functions and is therefore functionally different from the S- CC-Link interface.
- S-D4008 / AIO-1 — Analog I/O card for analog signal handling. It complements the control system but does not provide CC-Link networking.
- S-D4007 / PNET-1 — PSC network card. It provides a different network interface from the S- CC-Link card, so protocol requirements must be established before selecting between them.
- S-D4011 / SYNC-1 — Synchronous card used for synchronization functions. It is a timing/synchronization option rather than a network communication replacement.
- S-D4019 / PCNA-1 — ControlNet communication card listed among the PSC option cards. It is an alternative network technology, not a direct CC-Link substitute.
Procurement note: Treat , , and CCLK-1 as related identifiers, but confirm the actual board markings and system documentation before ordering. The strongest documented match is / S- / Part No. 173401.
