Introduction

The VersaMax® PLC family of products includes a broad range of small-size programmable
logic controllers (PLCs) with big-PLC features. The VersaMax family includes Nano PLCs (10
points), Micro PLCs (up to 176 I/O points), and Micro PLUS PLCs (up to 320 I/O points) using
optional Expansion Units. These small PLCs are the perfect solution for applications such as
packaging machines, dispensing machines, and relay replacement.

Figure 1

These versatile controllers provide powerful programming features such as built-in high-
speed counter functionality, support for floating-point function blocks and subroutines,
ability to assign passwords and privilege levels to control access, and override capability.
