Excellent PLC
Product Introduction
The Allen Bradley 2080-LC20-20QBBR Micro820 Programmable Controller is a compact, feature-rich programmable logic controller (PLC) designed for small-scale automation and smart control applications. As part of the Micro800 family, it integrates digital and analog I/O, communication interfaces, and advanced embedded features into a single, space-saving unit.
This controller is equipped with an embedded Ethernet port and a non-isolated RS-232/485 serial interface, enabling flexible connectivity with HMIs, drives, sensors, and supervisory systems. It supports 24 V DC digital inputs and source-type outputs, along with configurable analog inputs and a dedicated analog output channel, allowing it to handle both discrete and process control tasks efficiently.
Additional features such as an embedded real-time clock (RTC), MicroSD card support, and plug-in expansion slots enhance its versatility. The removable terminal block design simplifies installation and maintenance, making the 2080-LC20-20QBBR an ideal choice for OEM equipment and compact automation systems requiring reliable and scalable control.
