Automation PLC and Motion Components
Low Voltage PLC
Mrright supplies compact low-voltage PLCs with 24 V DC supply, designed for small and mid-size machines where panel space and budget are limited. These PLCs are stocked in Zhuhai and available as single units for immediate replacement of failed controllers.
Overview
What This Part Does in Your Machine
Mrright supplies compact low-voltage PLCs with 24 V DC supply, designed for small and mid-size machines where panel space and budget are limited. These PLCs are stocked in Zhuhai and available as single units for immediate replacement of failed controllers. Mixed orders with sensors, HMIs, and servo drives ship as one consolidated shipment.
Key Benefits
- Compact design fits tight control panels with limited space
- 24 V DC supply standard, compatible with most industrial sensors and actuators
- Single-unit orders accepted, avoiding factory minimums and long lead times
- Stock held in Zhuhai enables faster shipping than ordering direct from brand factories
- Mixed part lists including PLCs, sensors, HMIs, and drives ship in one delivery
Problems It Solves
- A failed PLC cannot be replaced quickly when the supplier requires a minimum order or long lead time
- Small machines often use low-voltage PLCs that are not stocked by large distributors
- Multiple suppliers are needed when combining PLCs with sensors, HMIs, and drives
- Shipping each part separately increases freight cost and delays commissioning
Who It Is For
- Machine builders working on small or mid-size machines with tight space constraints
- System integrators installing basic control logic on retrofit or custom cells
- Maintenance and MRO buyers replacing a failed controller without a minimum order
- Distributors consolidating low-voltage PLCs with other automation parts from China
Application
Where Low Voltage PLC Is Used
Application Scenarios
- Replacing a failed PLC on a small packaging machine where the original model is no longer available locally
- Adding control logic to a retrofit machine with limited panel space and a tight budget
- Building a new small automation cell that requires a basic controller with I/O and communication ports
- Holding a spare PLC on hand for a machine that cannot afford extended downtime
Technical Features
- Compact low-voltage PLCs with 24 V DC power supply
- Configurable I/O points for digital and analogue signals
- Transistor outputs capable of pulse train output for positioning applications
- RS485 or Ethernet communication ports for integration with HMIs or networks
- Support for expansion modules, allowing future upgrades without replacing the base unit
- Model selection based on I/O count, output type, and communication needs
Specifications
What Is Confirmed Before You Order
Values that depend on the model you choose are marked as confirmed on quotation rather than guessed at here.
| Supply voltage | 24 V DC |
|---|---|
| Power supply type | Low-voltage, compact form factor |
| I/O configuration | Varies by model - confirmed on inquiry |
| Output type | Transistor outputs with pulse train capability |
| Communication ports | RS485 or Ethernet - model dependent |
| Expansion support | Yes, expansion modules can be added later |
| Minimum order | Single unit accepted |
| Ships from | Zhuhai, Guangdong, China |
Checks Before Despatch
- Model number and I/O configuration verified against the customer's old controller or machine manual
- Power supply voltage and output type confirmed to match the machine's electrical requirements
- Packing list photographed before dispatch so the buyer can confirm contents
Customisation and Selection
- Model selected based on the I/O count, output type, and communication needs of the existing machine
- Expansion module compatibility checked before order confirmation
- PLC quoted with matching sensors or HMIs when part of a larger system upgrade
Comparison
How It Compares
| High-voltage or industrial-grade PLCs | Low-voltage compact PLCs use less space and are suitable for small machines where cost and panel size are critical |
|---|---|
| PLC bought from a brand factory directly | Single units and mixed brands are accepted here, and orders ship in one consolidated delivery |
| Generic or unbranded PLCs | Stocked models are from known brands with documented I/O and communication specs, reducing integration risk |
Use Guide
What to Send and What to Check
- Send the model number or a photo of the old PLC's nameplate
- Confirm the number and type of I/O points needed for your machine
- State whether you require RS485, Ethernet, or expansion module support
- Specify if pulse train output is needed for positioning control
Applications
Industries Using This Part
Plastics and Rubber Processing
Mrright supplies replacement and build parts for injection moulding and extrusion plants that use take-out robots and sprue pickers.
Electronics Assembly

Solutions
Solutions Built Around It
Control Retrofit and Panel Upgrade
An old machine still runs, but its controller cannot be bought any more. This is the parts side of a control retrofit.
Consolidated Automation Sourcing
One mixed parts list, one supplier, one shipment. This is how a bill of materials with eight brands on it is handled.

FAQ
Questions About Low Voltage PLC
Can I buy just one low-voltage PLC as a spare?
Yes. Single-unit orders are accepted. Send the model number or nameplate photo and we will confirm availability and price.
Do you carry multiple brands of low-voltage PLCs?
Yes. Several brands are held in stock in Zhuhai. Send the model you are replacing and we will confirm availability.
What do you need to quote a low-voltage PLC?
The model number or a nameplate photo, the required I/O count, output type, and communication port needs. We confirm compatibility before order placement.
Can I mix PLCs with sensors and HMIs in one order?
Yes. PLCs, sensors, HMIs, and drives are consolidated into one shipment, reducing freight cost and delivery time.
Are expansion modules available for these PLCs?
Yes, expansion modules can be added later. We confirm module compatibility when quoting the base unit.
