Delta Parts Supplier: PLC, Inverter, HMI and Servo Units, Including Obsolete Lines

When a Delta DVP PLC or a VFD inverter fails on a production line, the problem is rarely the price of the part. It is the lead time. Delta discontinues older series faster than many operators expect, and authorised channels will often only quote a current-generation replacement that needs re-wiring or re-programming. K2 Automation exists to solve the version of the problem authorised distributors cannot: sourcing the exact Delta unit you already run, in new, reconditioned or obsolete condition, and getting it to you with same-day dispatch where stock allows.

We hold and source across the full Delta industrial automation range, from PLC systems and inverter drives to servo motors and HMIs and displays. Send us a Delta part number and our team will confirm availability, condition and price, usually within one business day.

Why Source Delta Parts Through K2 Automation

K2 Automation is an independent supplier, not an authorised Delta Electronics distributor. That independence is the point. Because we are not tied to selling only current catalogue lines, we can source withdrawn and end-of-life Delta parts through a global network of specialists rather than pushing you toward a newer model. Every part, whether new, repaired or reconditioned, carries a minimum 12-month guarantee, and we supply from UK, US and German bases to keep international lead times short.

A Delta VFD failure on a packaging or textile line stops output entirely, so we treat machine emergencies as immediate-priority work and issue parts with same-day delivery when they are in stock. If you are running an obsolete Delta system that Delta no longer supports, we are frequently the practical route back to production.

Delta PLC Systems: DVP, AS and AH Series

A Delta PLC (programmable logic controller) is the sequential-control brain of a machine, handling logic, timing, counting and input/output across industrial automation equipment. Delta’s PLC families are built to integrate directly with its own drives, servo systems and HMIs over Modbus, CANopen, EtherCAT and PROFIBUS, which is why a like-for-like replacement matters so much: swapping series often means re-writing the program.

We source the ranges most likely to need replacement or lifecycle support, including:

DVP slim-DIN controllers such as the DVP-SS2, DVP-SA2, DVP-SX2, DVP-ES2, DVP-EX2 and the advanced DVP-EH3 with built-in motion and high-speed counters. AS-series mid-range rack PLCs including the AS218, AS228 and AS300 CPUs with EtherNet/IP and EtherCAT motion. AH-series modular PLCs for high-level process control and multi-axis motion. We also supply programming cables and I/O modules that are commonly the actual failed component rather than the CPU itself.

Browse the full Delta PLC range within our PLC systems category, or send a part number if the exact controller is not yet listed. Our Delta catalogue is still being populated, so absence from the page does not mean absence from our network.

Delta Inverters and VFD Drives

A Delta inverter, also called a Delta VFD (variable frequency drive), controls the speed and torque of an AC motor and is one of the most common Delta components to fail in the field. Because inverters sit directly in the power path, they take the brunt of voltage spikes, overheating and capacitor ageing, so demand for replacement units is high across the installed base.

We source Delta VFD inverters across the range, from fractional-kilowatt units such as the VFD-M, VFD-E, VFD-EL, VFD-L and VFD-S, through the compact MS300 and MH300 series, up to the high-power CP2000 and CH2000 drives rated to around 400 kW. Where a specific legacy inverter is genuinely unavailable, we will identify the correct functional equivalent rather than leaving you without a route forward.

See current stock in our inverter drives category. For drives that pair with motion control, our AC/DC drives and servo drives section covers the wider Delta drive family.

Delta Servo Motors and ASDA Servo Drives

Delta’s servo offering pairs ASDA-series drives (ASDA-A2, ASDA-A3 and ASDA-B3 amplifiers) with ECMA-series servo motors, typically from 100 W up to 7.5 kW, for precision motion control. These matched amplifier-and-motor pairs are exacting: a mismatched replacement will fault on power-up, so identifying the correct paired part is essential. Our team cross-references Delta catalogue numbers to confirm the amplifier and motor combination before you commit.

Explore available units in our servo motors category, and speak to us directly for obsolete ASDA drives that have left the current Delta line-up.

Delta HMIs and Operator Panels

Delta human-machine interfaces (HMIs) give operators the touchscreen link to the machine. The DOP-series panels, including the DOP-100, DOP-W and DOP-AE ranges from 4.3-inch to 15-inch, are the most widely deployed and the units we are most often asked to replace. A cracked or dead HMI does not usually mean the rest of the system is at fault, so a straight panel swap is frequently the fastest way back into production.

Find Delta operator panels in our HMIs and displays category.

Sourcing Obsolete and Discontinued Delta Parts

Delta withdraws older PLC, inverter and servo series on a rolling basis, and once a part reaches end-of-life the authorised channel typically directs you to a newer model. For an operator with a working machine, that means unwanted cost, re-wiring and re-programming for a fault that only needed a single like-for-like part.

K2 Automation specialises in exactly this gap. Through our global network of specialists and years of sourcing experience, we locate obsolete Delta units, from discontinued DVP PLCs to withdrawn VFD inverter frames, and supply them as new-old-stock, repaired or reconditioned parts under a 12-month guarantee. If you are running a legacy Delta system, tell us the part number and the machine it sits in, and we will confirm what we can source.

Delta Industrial Automation: One Integrated Ecosystem

Delta Electronics, founded in Taiwan in 1971, has grown into one of the largest industrial automation manufacturers in Asia, with a portfolio spanning PLCs, VFD inverters, servo systems and HMIs designed to work together as a single Delta Solution. Application code is portable between built-in PLCs in VFDs or HMIs and the full scalable PLC range, which is why keeping a system on matched Delta parts protects your existing programming investment.

On the software side, Delta PLCs are programmed with free tools: WPLSoft for the DVP series and ISPSoft or DIADesigner for the DVP, AS and AH ranges, all following the IEC 61131-3 standard. We supply the hardware; the programming software is available directly from Delta’s download centre at no cost, which is worth knowing before you replace a controller you assumed needed a paid licence.

Delta Parts Supplier FAQs

Is K2 Automation an authorised Delta distributor?

No. K2 Automation is an independent supplier and is not an authorised distributor, affiliate or representative of Delta Electronics. This independence lets us source obsolete and discontinued Delta parts that authorised channels no longer supply, rather than limiting you to current catalogue lines.

Can you supply obsolete Delta PLC and inverter parts?

Yes. Sourcing obsolete and end-of-life Delta parts is a core part of what we do. Using our global network of specialists we locate discontinued Delta PLCs, VFD inverters, servo drives and HMIs, and supply them as new, repaired or reconditioned units, each with a minimum 12-month guarantee.

How do I find the right Delta replacement part?

Send us the Delta part number, ideally with the machine or series it belongs to. Our team cross-references Delta catalogue numbers to confirm the exact unit, and where a legacy part is genuinely unavailable we identify the correct functional equivalent. This is especially important for ASDA servo drives, which must be matched to the paired ECMA motor.

Do you deliver Delta parts to the UK and internationally?

Yes. We supply Delta parts from UK, US and German bases with express delivery, and issue in-stock parts with same-day dispatch for machine breakdowns. Order tracking is provided on shipments. Contact our team to confirm lead times for your location.

What Delta product types does K2 Automation cover?

We cover the full Delta industrial automation range: PLC systems, inverter drives, servo motors and HMIs and displays. If you cannot see a specific Delta part listed, our catalogue is still being populated, so contact us with the part number.
