{"id":"automationdirect-gs4-23p0","model_id":"GS4-23P0","name":"AutomationDirect GS4-23P0","summary":"The AutomationDirect GS4-23P0 is a DURApulse GS4 series AC variable frequency drive in a NEMA 1 enclosure. It operates from 230 VAC input, with a 3 hp rating for 3-phase input and 1 hp for 1-phase input, and uses SVC or V/Hz control. It has an RS-485 port, integrated dynamic braking, and built-in Safe Torque Off (STO).","study_notes":["Input is 3-phase or 1-phase at 230 VAC; output is 3-phase. Rated 3 hp with 3-phase input and 1 hp with 1-phase input.","Amperage rating is 10 A with 3-phase input and 5 A with 1-phase input; variable-torque rating is 11 A.","Control mode is SVC or V/Hz; output frequency range is 0.1–599 Hz and carrier frequency range is 2–15 kHz.","RS-485 (RJ12) port supports Modbus RTU, Modbus ASCII and BACnet at up to 115.2k baud.","Optional EtherNet/IP and Modbus TCP cards are available.","Integrated dynamic braking; reverse capability built-in; internally bypassed: no; integrated EMI filter: no.","Analog I/O: 3 input channels (0–20 mA and 4–20 mA, ±10 VDC, 11-bit) and 2 output channels (0–20 mA and 4–20 mA, 0–10 VDC, 10-bit).","Discrete I/O: 8 sinking/sourcing 24 VDC inputs and 4 relay/sinking/sourcing outputs rated 240 VAC and 48 VDC; two Form C (SPDT) relays.","Programming language: ladder; connector type: screw terminals; for use with 3-phase induction motors.","Enclosure type is NEMA 1; mounting is panel or wall."],"safety_notes":["Safe Torque Off (STO) is built-in.","UL Listed File # E198015.","CE declarations are available; RoHS status is Yes; EU REACH document is available.","User-supplied external fuse required."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/high-performance_vfds/gs4-23p0","title":"DURApulse AC High-performance Drive: 230 VAC, 3hp with 3-phase input, 1hp with 1-phase input, (VFD) (PN# GS4-23P0) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS4-23P0_cutsheet.pdf","title":"GS4 23P0 cutsheet","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":9,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"vfd","manufacturer":"automationdirect","controllers":[],"supply_voltage":"230 VAC","frame_size":"A","output_type":"PWM output","ip_rating":"IP20","operating_temp_min_c":-10,"operating_temp_max_c":50,"joints":[],"protocols":["modbus-rtu","modbus-ascii"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/automationdirect-gs4-23p0","license":"https://creativecommons.org/licenses/by/4.0/"}
