The Micro 28 PLC is big on features with the built-in 28 I/O (expandable to 140 I/O) points
to fast cycle times, two built-in serial ports, robust instruction set, and generous memory
to allow more flexible programming. And it’s all packaged in a sturdy modular design for
easy access and long-term durability. This all-in-one PLC gives you everything you need
to control a wide variety of applications.
