Din Rail Mount Hybrid Motor Starters (DRMS)

Sensata Crydom's DRMS are compact devices and can provide up to six functions in the same unit. These include forward/reverse, soft start/soft stop, motor overload protection, and mains isolating relay. Their motor overload detection is based on a thermal load curve. The relays are de-energized when an overload condition is present, ensuring a long service life.

Features
  • 3-phase motors reversing up to 4 kW
  • 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 24 VDC 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
