# AutomationDirect GS4-22P0

Hardware · `GS4-22P0` · verification: source checked

The GS4-22P0 is a DURApulse GS4 series AC variable frequency drive rated for 230 VAC. It delivers 2 hp with a 3-phase input and 3/4 hp with a 1-phase input, using either sensorless vector control (SVC) or V/Hz control. It is built in a NEMA 1, IP20 enclosure with an A frame, has integrated dynamic braking, and communicates over RS-485.

## Safety

- Safe Torque Off (STO) is built-in.
- UL Listed, file # E198015; UL Recognized and UL Hazardous file numbers are listed as none.
- CE declaration available and RoHS status is Yes (see CE document); EU REACH document available.
- Enclosure is NEMA 1 with IP20 rating, so it is not protected against water or dust ingress.
- Operating temperature rating is -10 to +50 deg C; mounting is panel or wall.

## Study notes

- Supply and output voltage are both 230 VAC; input may be 3-phase or 1-phase, output is 3-phase.
- Amperage rating is 7.1 A with 3-phase input and 3.2 A with 1-phase input; variable torque rating is 8 A.
- Control mode is selectable between SVC (sensorless vector control) and V/Hz.
- Carrier frequency range is 2-15 kHz; output frequency range is 0.1-599 Hz.
- RS-485 port uses an RJ12 connection and supports speeds up to 115.2k baud.
- Port protocols listed are Modbus RTU, Modbus ASCII and BACnet; BACnet has no matching reference id in this schema.
- Optional EtherNet/IP and Modbus TCP cards are available and are not built in.
- Integrated dynamic braking and built-in reverse capability are included; the drive is not internally bypassed and has no integrated EMI filter.
- Analog I/O: 3 input channels (11-bit, 0-20 mA / 4-20 mA, +/-10 VDC) and 2 output channels (10-bit, 0-20 mA / 4-20 mA, 0-10 VDC).
- Discrete I/O: 8 sinking/sourcing inputs at 24 VDC and 4 relay/sinking/sourcing outputs at 240 VAC or 48 VDC, rated 3 A/point relay and 50 mA/point discrete.
- Programming language is ladder; GSLOGIC drive PLC software and GSOFT2 configuration software are listed for the series.
- Intended for use with 3-phase induction motors; connector type is screw terminals and the fuse is user-supplied external.
