Industrial Applications
Emergency Shutdown (ESD) Systems: The 3501T is primarily deployed in TMR (Triple Modular Redundancy) architectures for ESD. Its high-voltage range (90-155 VAC/VDC) is optimized for monitoring heavy-duty valve actuators and safety interlocks in Oil & Gas upstream/downstream facilities.
Burner Management Systems (BMS): The module handles 120V AC/DC feedback signals common in boiler and furnace control. The non-commoned, isolated point design is critical for detecting individual flame-scanner and limit-switch states without common-mode failure risks.
High-Reliability Power Distribution: Used in electrical substation monitoring where DC battery banks (110V/125V) serve as the primary control power. The 155V peak tolerance provides sufficient headroom for battery charging over-voltages.
Fire & Gas (F&G) Logic: Suitable for processing discrete signals from smoke, heat, and gas detectors. The fast <8ms detection time ensures that the safety system initiates mitigation protocols (deluge/isolation) with minimal latency.
Overcoming System Obsolescence
The manufacturer told you your control system is "End-of-Life." They want a full-scale migration. But your hardware is still robust—it just needs that one specific, hard-to-find module.
Amikon Limited specializes in the "Impossible."
We are global leaders in Obsolescence Management. We've built our reputation on sourcing the discontinued HMIs, PLCs, and VFDs that the original manufacturers have walked away from.
Extend System ROI: Why spend millions on a new system when we can provide the certified spares to keep your current line running for another decade?
Verified Reliability: We stock the heavyweights—ABB, Bently Nevada, Honeywell, Allen-Bradley, and Siemens.
Human-to-Human Support: Get a technical quote in 30 minutes, not 3 days.
Don't be forced into an upgrade you don't need. Salvage your uptime with Amikon.
Rapid Response Supply Chain
Let's be honest: when a PLC fails or a DCS module goes dark, you don't have weeks to wait for a factory backorder. You need that part yesterday.
At Amikon, we've spent years stockpiling 50,000+ high-demand modules specifically to bypass global supply chain bottlenecks. While others give you excuses, we give you a tracking number.
Inventory Power: From Bently Nevada 3500 racks to Honeywell Experion cards—if it's critical, we probably have it.
Condition: We deal strictly in New & Original hardware. No refurbished "surprises," no counterfeits.
The 1-Year Assurance: Every serialized component comes with a full 12-month replacement warranty.
Logistics Velocity: Partnered with DHL, FedEx, and UPS for door-to-door global express.
