Compatible Replacement & Equivalent Models
When the original S-D4007-E is unavailable or discontinued, the following models may serve as functional equivalents or drop-in replacements depending on your system configuration. Always verify firmware and hardware revision compatibility before substitution.
- RELIANCE S-D4007 – Base variant; functionally equivalent in most RELIANCE drive systems
- RELIANCE 0-57400 – Common cross-reference in legacy RELIANCE AutoMax systems
- RELIANCE 0-57401 – Enhanced revision; check slot and backplane compatibility
- Allen-Bradley / Rockwell equivalent – Consult cross-reference table; RELIANCE was acquired by Rockwell Automation
- Custom equivalent sourcing available – contact Konmask.com with your system model number
Why Choose the Original Model
- Proven field reliability in legacy RELIANCE drive and AutoMax control systems
- Exact firmware compatibility – no re-programming or parameter migration required
- Minimized downtime risk – direct swap without system reconfiguration
- OEM traceability – original part numbers maintained for audit and compliance records
- Long service life – industrial-grade components rated for continuous duty cycles
Typical Applications
- RELIANCE AutoMax distributed control systems
- AC/DC drive control and feedback loops
- Paper, steel, and material handling production lines
- Mining and heavy industrial process automation

System Compatibility
The S-D4007-E is designed for use within RELIANCE ELECTRIC AutoMax and compatible drive control architectures. Key compatibility considerations:
- Verify rack/backplane slot type matches your existing chassis
- Confirm firmware revision aligns with your controller software version
- Check power supply rating of the host rack before installation
- Post-Rockwell acquisition units may require updated configuration software – consult your system integrator
Selection Guide
Use the following decision framework to select the correct module for your application:
- Step 1 – Identify your system: Confirm the host platform (AutoMax rack model, drive series, software version)
- Step 2 – Check part suffix: S-D4007-E vs. S-D4007 – the “-E” suffix typically denotes an enhanced or export revision; verify with your OEM documentation
- Step 3 – Assess condition requirement: New OEM stock for critical uptime applications; tested-used for budget-sensitive MRO needs
- Step 4 – Confirm lead time: Contact Konmask.com for real-time stock availability and lead time before committing to a replacement path
- Step 5 – Request datasheet: We provide OEM datasheets and wiring diagrams upon request for qualified buyers

Replacement & Compatibility FAQ
Q: Is S-D4007-E the same as S-D4007?
A: They share the same base design. The “-E” suffix may indicate a hardware revision or export variant. Contact us to confirm interchangeability for your specific system.
Q: Can I use a Rockwell/Allen-Bradley module as a replacement?
A: Potentially yes, as RELIANCE was acquired by Rockwell Automation. However, direct substitution requires careful cross-referencing of I/O mapping, firmware, and physical form factor.
Q: Do you provide a warranty?
A: Yes. New units carry OEM warranty terms where applicable. Refurbished units include a 90-day functional warranty from Konmask.com.
Q: How long does shipping take?
A: Typically 3–7 business days internationally via DHL/FedEx Express. Contact us for urgent requirements.
Q: Can you source discontinued RELIANCE parts?
A: Yes. Konmask.com specializes in legacy and hard-to-find industrial automation components. Submit your part number for a sourcing inquiry.
