Designed for Indian conditions
Wide-input power, 55°C panel ratings, conformal-coated boards. We design for brownouts, dust and heat because that's where our devices live.
Automation devices, engineered in India.
Control hardware that runs when the line can't stop.
Servonix designs and manufactures PLCs, HMIs, servo drives, sensors and IIoT gateways — built in Pune, rated for Indian power and Indian heat, and backed by engineers who pick up the phone.
Burned-in before it's boxed.
48 hours powered, cycling, and hot — every unit, every time. Weak hardware fails in our building, not on your line.
Spares you can still buy in ten years.
Designed-in stays buyable. A ten-year spares commitment on every product we ship.

Who we are
We make the devices your machines depend on.
For fifteen years Servonix has built automation hardware for factories that measure downtime in lakhs per hour. Every PLC, drive and gateway is designed in-house, burned-in before it ships, and supported by the same people who engineered it — no overseas ticket queue, no week-long wait for a replacement card.

Why Servonix
Why plants standardise on Servonix
Automation hardware lives a hard life — vibration, dust, voltage swings, 50°C panels. We engineer for that life, not for a datasheet.
The manufacturer is your support line
When you call, you reach the people who designed and built the device — not a distributor reading a script three borders away.
Repairable, not disposable
Boards you can service, spares we stock for a decade, and documentation that lets your team troubleshoot. Hardware should outlive the warranty.
Made and stocked in Pune
A failed card can ship same-day from our facility. No customs, no eight-week ocean freight, no 'currently unavailable'.

Process
From requirement to running line
A clear, engineer-led path — so you always know what's specified, what's built, and what's been proven.
- 1
Consult
We learn your application, sequence, environment and constraints — on a call or on your floor.
- 2
Specify
We propose the devices and architecture, with a firm BOM, a real lead time, and the trade-offs spelled out.
- 3
Build & burn-in
Devices are manufactured, panels wired, programs written, and everything burned-in and tested before dispatch.
- 4
Commission
Our engineer is on site (or on a screen-share) until the line runs your sequence and makes good output.
- 5
Support
Spares, firmware, register maps and a direct line — for the life of the hardware.

Tension control for film winding
Closed-loop servo tension control that cut film breaks dramatically.
IIoT · 2024
Plant-wide OEE with EdgeLink
Connected 22 machines and surfaced real downtime reasons in weeks.

Testimonials
What plant and project engineers say
“Their drive sizing was the first time a vendor actually asked about our load instead of reading a catalogue number. Cycle time dropped 14%.”
Vikram IyerPlant Manager, packaging
“We retrofitted four obsolete-PLC machines with Servonix. Same machines, controls we can finally support — and they planned it around our shutdown.”
Anita SalunkeEngineering Head, textiles
“EdgeLink showed us our real downtime in a week. Turned out our 'machine problem' was a changeover problem. That one dashboard paid for itself.”

The two-year, no-fine-print warranty
Every Servonix device carries a 24-month warranty. If it fails in normal service, we repair or replace it — and if a designed-in unit is out of stock, you get a drop-in equivalent. No RMA maze, no 'end of life' surprises.
FAQ
Questions engineers ask us
Specs, support, lead times and compatibility — answered plainly.
Do your devices work alongside our existing PLCs and drives?
Yes. Our controllers, I/O and gateways speak the common industrial protocols — Modbus, OPC-UA, Profinet and serial — so they drop into a mixed-vendor plant. EdgeLink in particular is designed to bridge old and new.
What's the warranty, and what happens if a device fails?
Every device carries a 24-month warranty. If it fails in normal service we repair or replace it, and because we manufacture in Pune, a replacement can often ship same or next day — no customs, no long wait.
What if a product goes end-of-life — can we still get spares?
We commit to spares and drop-in replacements for ten years from a product's last ship date. If a unit is ever unavailable, we provide a compatible equivalent. Designed-in stays buyable.
Can you build hardware under our own brand?
Yes — OEM and private-label manufacturing is a core part of what we do. Your enclosure, label and optionally firmware, built and burned-in on our floor. We'll prototype before any volume commitment.
Do you only sell devices, or do you do engineering too?
Both. Beyond catalogue devices we design and build control panels, program PLCs and HMIs, engineer drive and motion systems, and commission complete solutions on site.
Where are you based, and do you support sites outside Pune?
Design and support are in Kharadi, Pune; manufacturing and burn-in in Bhosari. We support sites across India through field engineers and remote diagnostics, and ship devices nationwide.
Got a line that can't afford to stop?
Send us the device, the panel, or the problem. We'll tell you honestly whether we're the right fit — and quote a real lead time.
