  2. AC input card, or
  3. combination DC I/O card.
Ethernet communications option module

High speed communication interfaces:

  • Serial MODBUS RTU/ASCII and BACnet protocols built in,
  • Optional MODBUS TCP, EtherNet/IP communication cards
Flange Mounting option for better heat dissipation


GS4 QuickStart menus simplify configuration

The smart keypad is designed with defaults to quickly configure the drive, set the speed, start and stop the drive, and monitor critical application parameters. Up to four drive configurations can be stored in the keypad, and transferred to additional DURApulse GS4 drives. Users can also store up to 32 parameters in a custom Quick-Start menu.

  • Fire mode, Circulatory control mode
  • Field upgradeable firmware
  • Flange mount capability for better cooling:
