The I/A Series MicroNet 100, 150, and 200 Controllers are interoperable controllers designed in accordance with LonMark® guidelines. When programmed using WorkPlace Tech Tool, or loaded with a pre-engineered application, these controllers provide control for packaged rooftops, heat pumps, fan coils, unit ventilators, and similar applications. Controllers feature Sensor Link (S-Link) support, LED indication, screw terminal blocks, as well as DIN rail or panel mounting ability. These controllers can function in either standalone mode or as part of a LonWorks® TP/FT-10 Free Topology communications network. The 100, 150, and 200 series controllers use the same physical packaging, but differ in the onboard I/O points they provide.
