DRMS SERIES
DIN RAIL MOUNT HYBRID MOTOR STARTERS
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
• 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

GENERAL NOTES
All parameters at 25°C unless otherwise specified.
To achieve maximum ratings there must be a minimum spacing of 0.9 in (22mm) between the devices in free air (see derating curves).
(3)
For reliable operation the 24 VDC auxiliary power supply needs to be fully stable during the entire operation of the device. Removing this volt-
age while the output is under load could cause permanent damage to the device.
