Product Overview

The ABB 1TNE968900R1210, also designated as the PM564-R A0 and more accurately identified in official documentation as the PM564-R-ETH, is a compact and highly integrated programmable logic controller (PLC) CPU module engineered by ABB for the AC500-eCo series. This “ECO” variant is purpose-built for small to medium-scale industrial automation applications, offering a cost-effective entry point without sacrificing core functionality. As the central processing unit of the AC500-eCo system, the ABB 1TNE968900R1210 executes the user-defined control logic, processes field signals, and communicates with higher-level automation networks. Its unique value proposition lies in its rich, onboard mixed I/O capability: the ABB 1TNE968900R1210 integrates 6 digital inputs, 6 relay outputs, 2 analog inputs, and 1 analog output directly on the module itself, significantly reducing the need for external I/O modules in smaller control applications.

The ABB 1TNE968900R1210 is powered by a robust 24V DC supply and operates on the proven IEC 61131-3 programming environment via ABB Automation Builder. It is equipped with 128 kB of Flash program memory, which is fully sufficient for executing complex logic, timing, and sequencing tasks in applications such as packaging, material handling, and basic process control. The ABB 1TNE968900R1210 features a built-in RS485 serial interface (COM1) that supports Modbus RTU and CS31 protocols, enabling seamless integration with third-party field devices, HMIs, and drives. Furthermore, the ABB 1TNE968900R1210 can expand its capacity by connecting up to 10 additional S500 or S500-eCo I/O modules via the internal I/O bus, making it a scalable solution for growing automation needs.
