Siemens V23030-A1026-A104 Industrial Relay Module – Industrial Process Solution

Technical Overview & First Impression

From the perspective of a seasoned Industrial Solution Architect, few components carry as much operational weight as a precision switching relay embedded deep within a Distributed Control System. The Siemens V23030-A1026-A104 is precisely that kind of component — a high-reliability DPDT relay module engineered to serve as the critical interface between low-level control logic and high-power field devices in demanding Process Control environments. Whether deployed in a legacy DCS Hardware rack or integrated into a modern Fieldbus-based architecture, the V23030-A1026-A104 delivers the switching consistency that keeps industrial processes running without interruption.

From a technical compatibility standpoint, this relay’s 24V DC coil voltage and dual-pole double-throw contact configuration make it broadly interoperable across a wide spectrum of control panel designs. Its contact rating of 8A at 250V AC ensures it can handle both signal-level and moderate power-switching duties — a versatility that makes it a preferred choice when engineers evaluate Legacy Components for system upgrades or direct replacements in aging DCS Hardware installations.

What sets this unit apart in today’s constrained supply environment is its availability as a Factory Sealed, 100% original Siemens component. As global supply chains continue to tighten around discontinued and end-of-life industrial parts, sourcing a genuine V23030-A1026-A104 in new condition has become increasingly difficult. Our inventory represents a rare opportunity for maintenance engineers and procurement teams to secure this critical part before stock is exhausted.

Key Technical Highlights

DPDT Contact Architecture — Double Pole Double Throw configuration enables flexible circuit routing in both normally-open and normally-closed switching topologies, ideal for redundant control logic in Process Control systems.
24V DC Coil, ~640Ω Resistance — Optimized for direct interfacing with PLC digital output cards and DCS Hardware relay driver circuits without additional signal conditioning.
High-Speed Switching — Operate time 10ms, release time 5ms; supports high-frequency sequencing in automated production lines and Fieldbus-coordinated control loops.
Extended Mechanical Endurance — Rated for >20 million mechanical operations, ensuring long service intervals even in high-cycle Factory Sealed environments.
Wide Thermal Range — Operates reliably from -40°C to +85°C, covering arctic field installations through high-ambient industrial enclosures.
Multi-Certification Compliance — CE, UL, cUL, and VDE approvals confirm suitability for international deployments across North American, European, and Asian industrial facilities.

Vertical Industry Applications

Petrochemical & Refining: In refinery control rooms, relay modules like the V23030-A1026-A104 serve as the last line of switching logic between DCS output cards and field actuators. Their Factory Sealed condition ensures no contamination risk during installation in classified hazardous areas, directly reducing unplanned shutdown events.

Mining & Mineral Processing: Conveyor interlocking systems and crusher control panels demand components with exceptional mechanical endurance. The V23030-A1026-A104’s >20 million cycle rating makes it a natural fit for high-duty-cycle switching in ore processing facilities where downtime translates directly to lost tonnage.

Marine & Offshore Platforms: Shipboard automation and offshore platform control systems operate in corrosive, high-vibration environments. This relay’s robust construction and wide temperature tolerance support reliable operation in marine electrical panels, reducing the risk of control system failures far from shore-based maintenance resources.

Power Generation & Utilities: Turbine control systems and substation automation rely on Legacy Components that have proven track records. The V23030-A1026-A104 integrates seamlessly into existing relay panels, supporting both new installations and Maintenance Stock replenishment programs for aging power infrastructure.

Water Treatment & Municipal Infrastructure: SCADA-driven pump stations and treatment plant control panels require components with long operational lives and broad temperature tolerance. This relay’s electrical life of >200,000 operations at rated load supports multi-year deployment cycles without scheduled replacement.

Data Sheet & Specifications

Quality Assurance & Supply Chain

Every unit of the V23030-A1026-A104 supplied through our channel is 100% original Siemens manufacture — not refurbished, not rebranded, and not sourced from grey-market channels. Each relay arrives in its Factory Sealed original packaging, complete with manufacturer labeling and traceability markings that allow verification against Siemens production records.

Our 12-Month Comprehensive Warranty covers all manufacturing defects and material failures from the date of delivery. Should a unit fail within the warranty period under normal operating conditions, we provide direct replacement without bureaucratic delays — because we understand that in industrial environments, every hour of downtime carries a measurable cost.

For Emergency Repair scenarios, we maintain dedicated logistics partnerships with DHL Express, FedEx International Priority, and UPS Worldwide Express. Orders confirmed before daily cutoff times are dispatched same-day, with tracking provided immediately upon shipment. Whether your facility is in Southeast Asia, the Middle East, or Northern Europe, our global shipping network ensures the V23030-A1026-A104 reaches your maintenance team when it matters most.

Buyer’s FAQ — Selection Guide

Q: How can I verify that the V23030-A1026-A104 I receive is 100% original and not a counterfeit?
A: Authentic units carry Siemens-embossed housing markings, a laser-etched date code on the relay body, and original factory packaging with intact tamper-evident seals. Upon request, we can provide batch traceability documentation. If you have access to a Siemens authorized service center, the part number and date code can be cross-referenced against Siemens production databases.

Q: Where can I obtain the official datasheet for the V23030-A1026-A104?
A: The official technical datasheet is available through the Siemens Industry Online Support portal (support.industry.siemens.com) by searching the full part number V23030-A1026-A104. We can also provide a copy of the datasheet upon inquiry — contact our technical team directly.

Q: Is the V23030-A1026-A104 compatible with my existing DCS Hardware relay sockets?
A: This relay follows standard 8-pin DPDT footprint conventions compatible with widely used relay socket families. However, we strongly recommend verifying the pinout diagram against your existing socket before installation, particularly in legacy DCS Hardware panels where non-standard socket variants may have been used.

Q: Can this relay be used as a direct replacement in a Fieldbus-integrated control system?
A: Yes. The V23030-A1026-A104 functions as a passive switching element and is transparent to the Fieldbus communication layer. It interfaces at the physical output stage of the control system, making it compatible with PROFIBUS, PROFINET, and Foundation Fieldbus architectures without any protocol-level modifications.

Q: What is the lead time for emergency orders?
A: In-stock units ship same-day or next business day via DHL/FedEx/UPS Express. Estimated transit times range from 2-5 business days to most global destinations. Contact us directly for time-critical Emergency Repair requirements and we will prioritize your order accordingly.

Q: Is this part still in production, or is it an EOL (End-of-Life) component?
A: The V23030-A1026-A104 is classified as a Legacy Component within the Siemens relay portfolio. While Siemens may no longer actively promote this series, genuine new-old-stock units remain available through specialized industrial spare parts distributors. Securing Maintenance Stock now is strongly advisable for facilities with long-term dependency on this part.
