B&R and ABB PLCs: Flexible Control Solutions for Industry
Programmable logic controllers (PLCs) are the backbone of modern automation. They coordinate sensors, actuators and communication networks so factories, process plants and utilities run safely and efficiently. While ABB and B&R offer different PLC ecosystems, both brands are renowned for reliability and flexibility. Below we examine key modules from each platform, spotlight the ABB ACS 880‑11 Regenerative Single Drive and highlight alternatives available on our marketplace.
Why PLCs Matter
PLCs provide deterministic control of machines and processes. They handle digital and analog I/O, communication protocols and complex logic with high reliability and real-time determinism. Businesses choose PLC systems based on existing installed base, required performance and industry-specific functions (such as motion control, safety or redundancy). ABB’s AC500 family and B&R’s X20 series are popular choices because they scale from basic control tasks to sophisticated distributed automation.
Spotlight on ABB ACS 880‑11 Regenerative Drive
The ACS 880‑11 is a wall-mounted, regenerative single drive that minimizes energy waste and harmonics. The model ACS880‑11‑032A‑3 (product number 3AXD50000047494) delivers 15 kW at 400 V and 32 A. Key features include regenerative functionality (returns braking energy to the supply network instead of dissipating it as heat), Ethernet Powerlink option (+K470) for fast communication, and an active supply unit with a low harmonic line filter. This drive is ideal for applications with frequent braking, such as cranes, elevators or centrifuges. By returning energy to the grid, it reduces power consumption and lowers panel heat, leading to smaller cooling requirements.

ABB AC500 PLC Modules
ABB’s AC500 platform emphasises modularity. Controllers, communication interfaces, I/O modules and safety components can be mixed to suit any application. Notable modules include:
- PM5630‑2ETH Programmable Logic Controller Module – the core CPU for many AC500 systems, with 8 MB memory, integrated Ethernet, RS232/485 and CAN interfaces plus a display. It often includes a CM597‑ETH communication module (supporting TCP/P, UDP and Modbus TCP), a dummy coupler and a CPU terminal base with RJ45 slots.
- PM573‑ETH PLC Assembly – offers 512 kB memory, two RS232/RS485 ports and a 24 V DC supply with an SD slot. It includes a CM597‑ETH module for TCP/P, UDP and Modbus, plus a dummy coupler and IP20-rated CPU base.
- PM5670‑2ETH Programmable Logic Controller – features 160 MB memory with one serial and two Ethernet ports. It includes an SD slot, CAN interface, a display and bundles two CM579‑PNIO modules for PROFINET control with a TB5620‑TBA CPU base.
B&R X20 PLC System
B&R’s X20 series provides compact modules for distributed control. Highlights include:
- X20 CP 1583 CPU Module – an entry‑level controller with an Intel ATOM 333 MHz CPU and additional I/O processor. It offers onboard Ethernet, POWERLINK, USB and removable CompactFlash memory. With 128 MB DDR2 SDRAM and a slot for interface expansion, it matches the performance of larger controllers.
-
X20 DO 6322 Digital Output Module – six digital outputs with source connections, 2‑wire wiring and integrated output protection.
- X20 AI 4622 Analog Input Module – four inputs with ±10 V or 0–20 mA/4–20 mA ranges and 13-bit resolution.
- X20 AO 2622 Analog Output Module – two outputs selectable between current or voltage with 13‑bit resolution.
- X20 AO 4632 Analog Output Module – four outputs with 16‑bit resolution.
- X20 CS 1030 Communication Interface – adds an RS485/RS422 interface with integrated terminating resistor and ATEX Zone 2 compliance..
