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

  • Agriculture automation

Advantages for Conveyor

  • SIL-3 E-Stop contacts

  • 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)

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.
