SMC Dialog Plus Smart Motor Controller
Description When the Smart Motor Controller (SMC) was first introduced in
1986, its modular design, digital set-up, and microprocessor control
set the standard for soft starters. Since its launch in 1989, the SMC
PLUS

controller has been in a class by itself, providing unmatched
performance with innovative starting and stopping options. Now, the
SMC Dialog Plus

controller achieves a higher level of
sophistication with greatly enhanced protection, expanded
diagnostics, and the ability to log the motor’s operation (amps, kW,
and power factor), as well as the option to “dialog” with various
network protocols.
While the SMC Dialog Plus controller incorporates many new
features into its design, it remains easy to set-up and operate. You can
make use of as few or as many of the features as your application
requires.
The SMC Dialog Plus controller is a compact, modular, multi-
functional solid-state controller used in starting three-phase squirrel
cage induction motors and controlling resistive loads. The SMC
Dialog Plus product line includes current ratings from 24 to 1000
Amps, 200 to 600V, 50/60Hz. This covers applications up to 1000
horsepower. The SMC Dialog Plus controller meets applicabl
standards and requirements.
