MicroLogix 1200 System
MicroLogix 1200 System 3
MicroLogix 1200 controllers provide the computing power and
flexibility to solve a variety of applications utilizing the proven
MicroLogix and SLC 500 family architecture.
Available in 24 and 40-point versions, the I/O count can be expanded
using rackless I/O modules. This results in lower system cost and
reduced parts inventory.
A field-upgradable flash operating system ensures you will always be
up-to-date with the latest features, without having to replace
hardware. The controller can be easily updated with the latest
firmware via a web site download.
The MicroLogix 1200 controller utilizes Rockwell Software RSLogix
500 programming software and shares a common instruction set with
the MicroLogix 1000, MicroLogix 1500 and SLC 500 families of
controllers.
MicroLogix 1200 controllers with the additional communications port
called the Programmer/HMI Port (1762-LxxxxxR processors only) offer
advanced communications options, providing a clean, efficient
solution for applications requiring a network connection and HMI.

For dc voltage applications, the make/break ampere rating for relay contacts can be determined by dividing
28 VA by the applied dc voltage. For example, 28 VA/48V dc = 0.58A. For dc voltage applications less than 48V,
the make/break ratings for relay contacts cannot exceed 2A. For dc voltage applications greater than 48V, the
make/break ratings for relay contact cannot exceed 1A.
