Micro 870 – New, Larger Micro800 Controller

Welcome to part five of the nine part series covering my choices for the top new PLC and HMI products shown at Rockwell’s Automation Fair 2017.

Note: While this series covers the products in which I’m most interested, you’ll find all the new products listed in Rockwell’s guide HERE.

The New Micro 870:

Due out in February 2018, Rockwell describes its new Micro870 controller as leveraging the same footprint as the 24 point Micro850, but with greatly increased capacity.

Like the above mentioned Micro850, the new Micro870 will support three plug-in modules, but will increase the support of expansion I/O modules from four to eight.

The Micro870 will also have double the program and data memory of the Micro850, greatly expanding its ability to control complex applications.

A tale of two models:

The 2080-LC70-24QWB’s built-in I/O will consist of fourteen 12 or 24 volt (AC or DC) inputs, and ten Relay outputs.

The inputs will also support up to 4 two or four wire HSCs. Due to the inclusion of Relay outputs, this model will not support any PTOs or Motion Axes.

The 2080-LC70-24QBB’s built-in I/O will consist of fourteen 12 or 24 volt (AC or DC) inputs, and ten 24vdc Sourcing outputs.

The inputs can be used to support up to 4 two or four wire HSCs, while the 24vdc sourcing outputs will support up to two PTOs that can be used as Motion Axes.

The Micro870 will share all the other features with the Micro850, with the exception that it will require the use of Connected Components Workbench release 11 or later.

So what do you think?

Do you currently run out of memory or I/O when using the Micro850?

Or will this new expanded Micro800 controller finally be large enough for you to use in your systems?
