Allen Bradley Micro820 PLC

Our Micro 820 Programmable Logic Controller Systems include a nano-sized footprint and are designed for small standalone machine control and remote automation applications that require flexible communications and I/O capabilities. These controllers support up to 36 I/O points with many embedded features such as Ethernet, microSD slot for recipe and data log, and analog I/O.

The new Allen-Bradley Micro820 20pt controller is specifically designed for small standalone machines and remote automation projects with embedded Ethernet and Serial ports. It can function as a RTU (remote terminal unit) for remote machines with support for Modbus RTU and

TCP. It has embedded support for 4 thermistor temperature inputs for use as a DDC (direct digital controller) for Building Management Systems.

The Micro820 supports an embedded microSD slot that can be used for storing large amounts of data that normally cannot fit into memory for applications that require datalog and recipe. All files are stored in CSV text format for easy viewing and editing. The microSD card is also

used for backing up and restoring the program, which can be used for duplicating the program in several machines.

The Allen-Bradley Micro800 Remote LCD Display connects to the controller’s embedded RS232 port and works as an essential accessory for the Micro820 controller. With 4 or 8 lines of ASCII text and a tactile keypad, it can be used as a simple HMI. Its system menu is available in multiple languages for direct viewing and editing of controller variables. Controller’s Ethernet address can also be easily set from the menu. Supports front panel mounting as well as DIN rail mounting next to the controller.
