Key Takeaways
- RB Automation is an authorised Schneider Electric partner and supplies Modicon controllers in Ahmedabad.
- We also supply Rtelligent RX3U, RX8U and RM500 PLCs, remote I/O and EtherCAT couplers, and PLC-HMI combos.
- Choose a PLC by I/O count, pulse or motion needs, communication and future expansion.
- We supply the HMIs, drives and sensors around the PLC, and build control panels.
The PLC is the heart of every automated machine and process line. Choosing the right one affects wiring, motion control, communication with drives and HMIs, and how easily the system can grow later. As a PLC supplier in Ahmedabad, RB Automation supplies Schneider Electric and Rtelligent controllers and helps you pick the right platform for the job.
PLCs and Controllers We Supply in Ahmedabad
Schneider Electric Modicon
As an authorised Schneider Electric partner we supply industrial machine controllers, process controllers, motion controllers and distributed I/O. See the Schneider PLC page. We also supply Harmony HMIs such as the ET6 and GTO, and Citect SCADA.
Rtelligent PLCs and motion controllers
- RX3U pulse-type small PLC for machines that drive steppers and servos with pulse outputs.
- RX8U small PLC.
- RM500 PLC/motion controller with EtherCAT for multi-axis machines.
- Card-type remote I/O modules and the REC1 EtherCAT coupler.
PLC-HMI combo units
The MX3G-43C-22MT and MX3G-70C-48MT put a PLC and touch screen in one unit, a space- and cost-saving choice for small machines. See PLC-HMI combo.
How to Choose a PLC
- I/O count: digital and analogue inputs and outputs today, plus spare for changes.
- Motion: high-speed pulse outputs for steppers and servos, or EtherCAT for multi-axis motion.
- Communication: Modbus, Ethernet or a fieldbus to talk to drives, HMIs and SCADA.
- Process or machine: process plants need analogue loops and redundancy options; machines need speed and motion.
- Standardisation: many plants prefer one platform across lines for spares and programming.
- Expansion: remote I/O lets you add points without rewiring the main panel.

PLC Applications Around Ahmedabad
Process plants in Naroda and Vatva use PLCs with analogue inputs for pressure, level and temperature control. Pharma and packaging plants around Changodar and Moraiya need PLCs with motion and HMI integration; our PLC and HMI for pharmaceutical machines article covers this. SPM builders in Odhav and Kathwada often use a pulse-type PLC with steppers or servos, while auto plants near Sanand standardise on networked controllers and remote I/O.
Control Panels and Integration
Beyond supplying the PLC, we build PLC control panels and customised automation solutions, and supply the drives, sensors and transmitters that connect to them. See our AC drive guide and servo drive guide for Ahmedabad.
PLC Options Compared
| Option | Brand | Best for |
|---|---|---|
| Modicon industrial machine controllers | Schneider Electric | Machine builders standardised on Schneider |
| Modicon process controllers | Schneider Electric | Process plants with analogue loops |
| Modicon motion controllers | Schneider Electric | Synchronised multi-axis machines |
| RX3U pulse-type small PLC | Rtelligent | Machines driving steppers or servos by pulse |
| RX8U small PLC | Rtelligent | Compact machine control |
| RM500 PLC / motion controller | Rtelligent | EtherCAT multi-axis machines |
| MX3G-43C-22MT / MX3G-70C-48MT | PLC-HMI combo | Small machines needing a PLC and touch screen in one unit |
Machine PLC vs Process PLC
| Need | Machine automation | Process automation |
|---|---|---|
| Main signals | Digital I/O, pulse outputs, fieldbus | Analogue inputs from transmitters, PID loops |
| Priority | Fast scan and motion | Stable control, alarms and trends |
| Typical add-ons | HMI, servo and stepper drives | SCADA, transmitters, VFDs |
A Typical PLC Application in Ahmedabad
A typical batch reactor in a Vatva chemical unit uses a PLC to read pressure, temperature and level transmitters, run the agitator through a VFD, open and close feed valves in sequence and raise alarms. An HMI on the panel lets operators start batches and see trends, and a SCADA PC in the control room logs every batch. At the other end, an SPM builder in Odhav may need only a pulse-type PLC driving three stepper axes and an HMI for recipes. The right controller depends on which of these your system looks like.
Common PLC Selection Mistakes to Avoid
- Ordering exactly the I/O needed today with no spare.
- Choosing a PLC without enough high-speed pulse outputs for the motion axes.
- Ignoring the communication protocol of the drives and HMIs already on site.
- Mixing many PLC brands across one plant, which complicates spares and programming.
What to Send for a PLC Quote
- Digital and analogue I/O count
- Motion axes and drive type
- Communication needed (Modbus, Ethernet, EtherCAT)
- HMI or SCADA requirement
- Preferred brand, panel build needs and quantity
Why Choose RB Automation
An authorised Schneider Electric partner and Rtelligent's technical partner, we can recommend a Schneider platform where the plant standardises on it, or a cost-effective Rtelligent PLC for OEM machines. Our office in Jagatpur and facility in Kathwada support customers across the city. See the full automation range we supply in Ahmedabad.
Conclusion
The right PLC depends on I/O, motion, communication and how your plant standardises. Share your machine or process details with RB Automation in Ahmedabad and we will recommend a Schneider or Rtelligent controller.

Frequently Asked Questions
Which PLC brands do you supply in Ahmedabad?
We supply Schneider Electric Modicon controllers as an authorised partner, Rtelligent RX3U, RX8U and RM500 PLCs and motion controllers, remote I/O, the REC1 EtherCAT coupler, and MX3G PLC-HMI combo units.
Are you an authorised Schneider Electric partner in Ahmedabad?
Yes. RB Automation is an authorised Schneider Electric partner and supplies Modicon PLCs, Altivar drives, Harmony HMIs and Citect SCADA in Ahmedabad and across Gujarat.
Which PLC should I use with stepper or servo motors?
For a few axes, a pulse-type PLC such as the Rtelligent RX3U works well. For many axes or tight synchronisation, a motion controller with EtherCAT, such as the RM500, is a better fit.
