Overview
What This Part Does in Your Machine
Mrright supplies programmable logic controllers and expansion modules for machine control, held in stock in Zhuhai. Buyers select by I/O count, I/O type, supply voltage, communication port, and programming software. Single-unit orders are accepted, and mixed part lists including PLCs, HMIs, and sensors ship as one consolidated order. Quotations and orders are handled via WhatsApp and email.
Key Benefits
- PLC and expansion modules are quoted together, so I/O count and type match the machine requirement
- Single-unit spares are accepted, which avoids waiting for factory minimums
- Multi-brand stock in Zhuhai reduces lead time for obsolete or hard-to-source controllers
- PLC, HMI, and drive sets can be quoted and shipped as one consolidated order
- Before- and after-sales support is provided directly through WhatsApp and email
Problems It Solves
- A machine stops running because the original PLC is obsolete and no longer available from the factory
- A new I/O requirement forces a full control cabinet redesign when a simple expansion module would suffice
- Quoting PLCs, HMIs, and drives across multiple suppliers takes days and increases error risk
- Freight costs rise when each component ships separately from different suppliers
Who It Is For
- Machine builders specifying control hardware for new machines
- System integrators commissioning multi-component control cells
- Maintenance and MRO buyers replacing a failed or outdated PLC
- Distributors and trading houses consolidating automation parts from China
Application
Where Automation PLC and Control Devices Is Used
Application Scenarios
- Replacing an obsolete PLC on a machine where the original brand is no longer available locally
- Adding I/O capacity to an existing machine without redesigning the control cabinet
- Building a new machine where the PLC, HMI, and servo drives are quoted as a single integrated set
- Sourcing a controller for a retrofit project where the original PLC is no longer supported
Technical Features
- Programmable logic controllers with digital and analogue input/output options
- Expansion modules available for additional I/O, depending on the model selected
- Support for multiple communication ports including RS485 Modbus, Ethernet, and CANopen
- Programming software compatibility confirmed on quotation
- Multiple brands held in stock in Zhuhai, selected based on machine requirement

Checks Before Despatch
- Model number and I/O configuration checked against the customer's machine drawing or old nameplate photo before ordering
- Expansion module compatibility verified with the base PLC model before shipment
- Packing list photographed before dispatch so the buyer can confirm what shipped
Customisation and Selection
- PLC model selected based on an existing nameplate photo when the original part is obsolete
- I/O count and type confirmed against the machine's wiring diagram before the order is placed
- PLC, HMI, and drive sets quoted as a package with the control logic already aligned
Comparison
How It Compares
| Motor and drive without a PLC | A PLC integrates all control logic, so the machine runs without needing a separate controller |
|---|---|
| PLC bought from a factory direct | Single units and mixed brands are accepted here, and they leave in one shipment |
| Using a generic or unbranded controller | Branded PLCs ensure compatibility with existing software, communication protocols, and integration tools |
Use Guide
What to Send and What to Check
- Send a photo of the PLC nameplate or the model number from the machine manual
- Confirm I/O count, type, and supply voltage against the machine's wiring diagram
- State the required communication port and programming software before the order is confirmed
- Ask for the programming software and parameter list with the PLC so it can be set up on arrival

FAQ
Questions About Automation PLC and Control Devices
Can I buy just one PLC as a spare?
Yes. Single-unit orders are accepted. Send the nameplate photo or model number and the I/O configuration will be confirmed.
Do you carry the same brands as the original manufacturer?
Multiple brands are held in stock in Zhuhai. Send the model you are replacing and availability is confirmed by return message.
Can I mix PLCs with HMIs and sensors in one order?
Yes. PLCs, HMIs, sensors, and drives are consolidated into one shipment, reducing freight and handling.
What do you need to quote a PLC?
The model number or a nameplate photo, the required I/O count and type, supply voltage, and communication port. The destination port or city is also needed.
How long does it take to get a quote?
Quotes are handled via WhatsApp and email. Response time is within the same business day.
