AutomationDirect GS23-4025

The GS23-4025 is an enclosed DURApulse GS20 series general-purpose AC variable frequency drive. It takes a 460 VAC three-phase input rated 25 hp and drives three-phase induction or permanent magnet AC motors using SVC, V/Hz, FOC or torque control modes. It provides an RS-485 port with Modbus RTU/ASCII slave support, a USB B port, analog and discrete I/O, and integrated dynamic braking.

Study notes

  • Rated 25 hp with 3-phase input; 38 A rated current, 41.5 A in variable torque duty.
  • Control modes: SVC (sensorless vector control), V/Hz, FOC or torque mode.
  • Output frequency range 0.1–599 Hz; carrier frequency range 2–15 kHz.
  • Communication: (1) RS-485 (RJ45) and (1) USB B, speeds up to 115.2k baud, Modbus RTU Slave and Modbus ASCII Slave.
  • I/O: 2 analog inputs (0–20 mA / 4–20 mA, +/-10 VDC, 10-bit and 12-bit resolution), 1 analog output (0–20 mA / 4–20 mA, 0–10 VDC, 10-bit), 7 discrete inputs at 24 VDC sinking/sourcing, 3 discrete outputs (240 VAC and 48 VDC, relay/sinking/sourcing) including (1) Form C (SPDT) relay.
  • Load current 3 A per point for the relay output and 50 mA per point for discrete outputs; a user-supplied external fuse is required.
  • Integrated dynamic braking; the drive is not internally bypassed and has no integrated EMI filter.
  • Programmed in ladder; spring clamp terminals; keypad GS20A-KPD supplied attached to the drive.
  • Optional EtherNet/IP and Modbus TCP card available (communication card, not native to the drive).
  • Mounting is panel or wall; frame size F; item shipping weight 16.6 lb.
  • Brand DURApulse, series GS20, controller type general purpose.

Safety

  • Safe Torque Off (STO) is built in.
  • Enclosure IP rating is IP20, so the drive must be installed in a suitable enclosure environment.
  • Operating temperature rating is -20 to +50 deg C.
  • UL Listed, file # E198015; UL Recognized and UL Hazardous: none. CSA file: none.
  • RoHS status: Yes (see CE doc); CE declarations available; EU REACH document available.
