Sensata / Crydom DRMS Series (DIN Rail Mount AC Output) Solid State Relays

DRMS Series Hybrid Motor Starters

The DRMS Series Hybrid Motor Starters are intelligent and convenient solutions for controlling 3-phase asynchronous motors. These compact devices can provide up to 6 functions in the same unit: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay.

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
• alvanic 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
