Crydom / Sensata DRMS DIN Rail Mount Hybrid Motor Starters

Crydom / Sensata DRMS DIN Rail Mount Hybrid Motor Starters are an intelligent and convenient solution for controlling 3-phase asynchronous motors. These Crydom / Sensata devices provide up to 6 functions in the same unit, including Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay. When a motor overload condition is present based on a thermal load curve, the relays de-energize to ensure long service life.

Features

  • 3-phase motors reversing up to 4kW
  • 2-phase soft start/stop
  • Up to 4 dials for setting of starting torque, deceleration torque, soft start/stop, and rated motor current
  • 4 LEDs for status indication
  • Galvanic separated 24VDC inputs for forward and reverse control
  • Reset button on front, with connection for external reset
  • Relay indicator output for operation
  • Hybrid relay combines benefits of electromechanical relay technology with non-wearing semiconductor technology
  • High reliability by temperature monitoring of semiconductors

Applications

  • Reversing operation for door and gate controls, bridge drives, and lifting applications with monitoring of blockage
  • Conveyor systems with monitoring of blockage
  • Actuating drives in process controls with blockage monitoring
