The M100 starter is an advanced electro-mechanical motor starter that combines the functionality of a contactor and an overload relay into a smaller footprint. This starter series offers direct-on-line (DOL) and reversing electronic motor starters, with an option for SIL 3 Safe Torque Off (STO) functional Safety. M100 starters can control single- and three-phase motors up to 480V AC and are available with maximum current ratings of 9 A and 23 A. The M100 starter has integrated electronic overload protection, which eliminates the need for a separate overload relay.

The M100 starter requires a 24V DC control power source and uses 24V DC control signals. For control inputs, the M100 starter is equipped with start, stop, remote reset, and reversing (when applicable). Two separate, integrated 24V DC (100 mA max load) outputs signal the M100 starter and fault status. The M100 starter safety option requires two separate 24V DC OSSD safety demands, which must be provided from a compatible safety logic device.

The M100 starter features a user interface on the front of the unit for configuration and diagnostics. Light-emitting diodes (LEDs) indicate module and motor status and reversing and STO status when applicable. With the M100 starter DIP switches, you can switch between singleand three-phase control and select auto or manual overload reset. A full load ampere (FLA) selector dial is also installed on the front of the unit, which can be used to configure the M100 starter protection features.
