The ABB AC300 micro PLC (PM30 series) is a compact controller for small machines and simple process control. Models such as the PM3032-T-ETH combine built-in digital I/O with serial and Ethernet communication, and the system can be expanded with I/O modules as the application grows.
Highlights (PM3032-T-ETH example)
- 8 built-in digital inputs and 8 NPN digital outputs
- RS232 and RS485 serial ports for HMIs, VFDs and meters (e.g. Modbus RTU)
- Ethernet port for HMI/SCADA connection and programming
- USB Type-C port
- Expandable with up to 16 I/O modules
- 24 V DC supply
Where it fits
The AC300 suits OEM machines, pump and fan control, small utility skids and building services where a full AC500 system would be oversized. For larger systems, safety PLC needs or redundant control, the AC500 family is the better choice. We can help you size the I/O, choose expansion modules and integrate ABB drives over serial or Ethernet.
Typical applications
- OEM machine control
- Pump, fan and compressor sequencing
- Small water treatment and utility skids
- Control of ABB VFDs and softstarters over Modbus
Selection tips
- Count your I/O with 20% spare before choosing expansion modules.
- Check output type (NPN/sink) against your field devices.
- Use the RS485 port for Modbus RTU links to VFDs and energy meters.
- Move to AC500 for large I/O counts, safety or redundancy.
AC300 Micro PLC: frequently asked questions
How many I/O modules can the AC300 take?
The PM3032-T-ETH supports expansion with up to 16 I/O modules, in addition to its built-in 8 inputs and 8 outputs.
Can the AC300 communicate with ABB VFDs?
Yes. ABB drives with built-in Modbus RTU can be controlled from the AC300's RS485 port, and Ethernet can be used for HMI/SCADA connections.
AC300 or AC500 — which should I choose?
AC300 is for compact machines and small systems. AC500 is a scalable platform for larger I/O counts, high-performance and safety applications.
Do you provide PLC programming?
Yes. We supply the PLC and can program, panel-build and commission the complete system.
