RELIANCE S-D4006-D / S-D4006 – Digital Output Module | AutoMax PLC Platform
Engineering Background
The Reliance Electric AutoMax Distributed Control System was engineered for high-demand industrial drive and motion control environments — steel mills, paper machines, extruders, and heavy process lines. The AutoMax rack-based architecture separates I/O, communication, and processing functions into discrete plug-in modules, enabling modular expansion and simplified field maintenance. The S-D4006-D (also catalogued as S-D4006) is the platform’s dedicated digital output module, providing the discrete switching interface between the AutoMax controller and field actuators such as contactors, solenoids, pilot lights, and relay coils.
Product Positioning
This module is the preferred sourcing solution for maintenance engineers and OEM integrators who require a verified, drop-in replacement for aging AutoMax installations. Konmask.com maintains surplus inventory of this module to support facilities that cannot migrate legacy AutoMax systems on short notice. Each unit is inspected and function-verified prior to dispatch.

- Chemical & Petrochemical — Process interlocking and permissive logic executed through AutoMax digital output modules
- OEM Machine Builders — Retrofit and upgrade projects where AutoMax hardware must remain operational during phased migration
Engineering Advantages
- Direct Drop-In Replacement — Identical form, fit, and function to the original OEM module; no firmware changes or rack reconfiguration required
- Optical Isolation — Field-side isolation protects the AutoMax backplane from inductive load transients and ground loops
- Per-Channel LED Diagnostics — Immediate visual confirmation of output state accelerates fault isolation during commissioning and maintenance
- Proven Long-Term Reliability — AutoMax modules are known for robust construction suited to continuous industrial duty cycles
- Surplus Availability — Konmask maintains stock of discontinued AutoMax modules, eliminating lead-time risk for critical spares
System Architecture & Signal Flow
Within the AutoMax rack, the S-D4006-D occupies a standard I/O slot and communicates with the AutoMax processor module via the proprietary backplane bus. The processor writes output data words to the module’s internal register map. The module’s output driver circuitry converts these digital states to field-level switching signals, activating or de-activating connected actuators. Optical isolation at the field terminal boundary ensures that field-side wiring faults do not propagate to the controller backplane. Status LEDs on the module faceplate mirror the logical output state in real time, providing a hardware-level diagnostic independent of the programming terminal.
Sourcing & Quality Verification

- Inspection: Visual inspection for physical damage, connector integrity, and component condition
- Functional Test: Power-on and output channel verification prior to shipment where test fixtures are available
- Packaging: Anti-static bag + foam-lined carton; ESD-safe handling throughout
- Warranty: 90-day return-to-base warranty against DOA or latent defects
- Authenticity: All units are genuine Reliance Electric OEM hardware — no counterfeit or clone parts
Procurement Process
- Confirm Compatibility — Verify your AutoMax rack slot type and required output voltage/current against your existing system documentation or contact our technical team
- Request Stock Confirmation — Contact support@konmask.com or call +0086 19859288691 to confirm current inventory and lead time
- Place Order — Add to cart and complete checkout, or request a formal quotation for purchase order processing
- Receive & Install — Module ships in ESD-safe packaging; installation requires only powering down the rack, seating the module, and restoring power — no software configuration needed for direct replacement
Technical FAQ
Q: Is the S-D4006-D the same as the S-D4006?
A: Yes. The “-D” suffix denotes a minor revision designation used in some Reliance Electric documentation. Both part numbers refer to the same physical module and are interchangeable in AutoMax racks.
Q: Can this module be used in non-AutoMax Reliance racks?
A: No. The S-D4006-D is designed exclusively for the AutoMax rack backplane. It is not compatible with Reliance AUTOMAX 6000 or other Reliance rack families.
Q: Do you provide a test report or inspection certificate?
A: A basic inspection record is available on request. Contact our team before ordering if a formal test certificate is required for your procurement process.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Contact us to confirm current availability before placing a time-critical order.
Q: Can you supply multiple units for a spares program?
A: Yes. Volume pricing is available for quantities of 3 or more. Contact support@konmask.com for a bulk quotation.
