RELIANCE S-D4007-E / S-D4007 – Network S Module | AutoMax DCS Platform
Engineering Background
The Reliance Electric AutoMax Distributed Control System (DCS) was engineered for demanding industrial environments requiring deterministic, high-speed inter-controller communication. The S-D4007-E (enhanced revision) and its predecessor S-D4007 are Network S Modules designed to integrate AutoMax controllers into a peer-to-peer token-passing network, enabling synchronized multi-axis coordination and real-time data exchange across the plant floor.
Product Positioning
Targeted at maintenance engineers and procurement specialists managing legacy AutoMax DCS installations in metals, paper, plastics, and heavy process industries, the S-D4007-E / S-D4007 provides a direct drop-in replacement path with full backward compatibility. Sourced, tested, and verified by Konmask.com — your trusted industrial automation parts partner.

Engineering Advantages
- Deterministic Token-Passing Network – Guarantees cycle-accurate data delivery critical for multi-axis drive coordination
- Direct Drop-In Replacement – S-D4007-E is backward compatible with S-D4007 installations; no firmware changes required
- Peer-to-Peer Architecture – Eliminates single-point-of-failure master controller dependency
- Proven Long-Term Reliability – Field-hardened design with decades of installed base in heavy industry
- Minimal Downtime Swap – Hot-swap capable within AutoMax rack architecture (verify with system documentation)
System Architecture & Signal Flow
The S-D4007-E / S-D4007 Network S Module occupies a dedicated slot in the AutoMax controller rack. It interfaces directly with the AutoMax backplane bus and connects to the plant-wide Network S coaxial or fiber ring. The token-passing protocol ensures each node transmits in a defined sequence, delivering deterministic latency suitable for closed-loop drive control. Data tables are shared across all network nodes, enabling any controller to read process variables from any other node without polling overhead.
Typical signal flow: AutoMax CPU ↔ Network S Module (S-D4007-E) ↔ Network S Ring ↔ Peer AutoMax Nodes / Drive Controllers

Technical FAQ
Q: What is the difference between S-D4007 and S-D4007-E?
A: The S-D4007-E is an enhanced revision with improved firmware and potentially expanded diagnostics. Both are functionally interchangeable in standard AutoMax Network S applications. Consult your AutoMax system manual for revision-specific feature differences.
Q: Is this module compatible with Rockwell Automation / Allen-Bradley systems?
A: The AutoMax platform was developed by Reliance Electric, later acquired by Rockwell Automation. The S-D4007-E is specific to the AutoMax DCS architecture and is not directly compatible with ControlLogix or CompactLogix platforms.
Q: Can I use this module to replace a failed network card in an active production system?
A: Yes. The S-D4007-E is designed as a direct replacement. Ensure the system is in a safe state before card swap. Refer to AutoMax Network S installation documentation for node address configuration procedures.
Q: Do you provide a warranty?
A: All units carry a 90-day functional warranty. Extended warranty options available — contact us for details.
Q: What is the lead time for international orders?
A: In-stock units ship within 1–2 business days. International delivery via DHL/FedEx Express typically 3–7 business days depending on destination.
