EATON - Electronic Motor Starter
With its EMS electronic motor starter, Eaton is setting a new standard by offering a multifunctional motor protection and control relay with a frame width of 30 mm. This electronic motor starter is intended for applications in which motors with a performance range from 0.06 kW to 3 kW need to be reliably driven and protected while using up as little space as possible.
Target applications
Logistics
Conveyor control
Production machines
Tooling machines
Packaging machines
Small elevators

E-Stop is required by Standard 1926.555 of the United States Department of Labor
Direct and reversing motor starter
Hybrid contact technology
High life span (30 Million switching cycles)
Avoids process / machine interruptions
Avoids device replacements
EMS interrupts the motor on all phases
No voltage on the output terminals in OFF (unlike semiconductor relays)
OFF
Contactor Isolation
Switching On
No make load on contacts
ON
No heat on SSRs
Switch OFF
No break load on contacts
Comparison to Standard Motor Control Combinations
Conventional wiring
Time intensive and error-prone wiring
Limited information about the process
Additional I/O level for controlling and monitoring devices
SmartWire-DT solution
Faster commissioning due to pluggable control wiring
Space saving via substitution of digital PLC I/Os
More information about the process and making it more stabile
Eaton’s SmartWire-DT is an intelligent machine wiring solution that reduces panel and machine wiring complexity by consolidating complex circuit wiring into a single cable. When assembling your machine, connecting components over SmartWire-DT is fast and simple both inside and outside the control cabinet. Once the machine is built, SmartWire-DT streamlines testing and reduces installation, commissioning and troubleshooting to save you time and money.
