Controller programmable 7Relay output 26.4VDC

The Allen-Bradley Micro820 20 point 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.
