# AutomationDirect GS23-55P0

Hardware · `GS23-55P0` · verification: source checked

The GS23-55P0 is an enclosed general-purpose AC variable frequency drive from the DURApulse GS20 series. It accepts 575 VAC three-phase input and runs three-phase induction or permanent magnet AC motors at 5 hp, using SVC, V/Hz, FOC or torque control modes. It has a built-in keypad, integrated dynamic braking, spring clamp terminals and an RS-485 port for Modbus RTU or ASCII slave communication.

## Study notes

- Control modes are SVC, V/Hz, FOC or torque; output frequency range is 0.1-599 Hz and carrier frequency range is 2-15 kHz.
- I/O: 7 discrete inputs (24 VDC, sinking/sourcing) and 3 discrete outputs (relay/sinking/sourcing), with one Form C (SPDT) relay.
- Analog: 2 input channels (0-20 mA, 4-20 mA, +/-10 VDC; 10-bit and 12-bit) and 1 output channel (0-20 mA, 4-20 mA, 0-10 VDC; 10-bit).
- Communication ports are one RS-485 (RJ45) and one USB B, with port speeds up to 115.2k baud.
- Input signal options are 4-20 mA, voltage, potentiometer or pulse train input; drive output is PWM.
- Programming language is ladder; connector type is spring clamp terminals; mounting is panel or wall.
- An optional EtherNet/IP and Modbus TCP card is available but is not a native port on this part number.
- Rated 6.6 A, with a variable torque rating of 8 A; reverse capability is built-in and the drive is not internally bypassed.
- No integrated EMI filter; an integrate dynamic braking circuit is included.
- UL Listed File # E198015; RoHS status Yes.
