{"id":"automationdirect-gs21-22p0","model_id":"GS21-22P0","name":"AutomationDirect GS21-22P0","summary":"The GS21-22P0 is an enclosed DURApulse GS20 series general-purpose AC variable frequency drive from AutomationDirect. It takes single-phase 230 VAC input and produces three-phase 230 VAC output for a 2 hp motor, using selectable SVC, V/Hz, FOC or torque control modes. It includes RS-485/USB communication, analog and discrete I/O, and integrated dynamic braking.","study_notes":["Input is 1-phase 230 VAC; output is 3-phase 230 VAC.","Motor rating is 2 hp with 1-phase input; rated amperage 7.5 A, variable torque amperage 8.5 A.","Control modes selectable: SVC, V/Hz, FOC or torque.","Communication ports are (1) RS-485 (RJ45) and (1) USB B, at speeds up to 115.2k baud.","Carrier frequency range 2–15 kHz; output frequency range 0.1–599 Hz.","Analog I/O: 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).","Digital I/O: 7 discrete inputs (24 VDC, sinking/sourcing) and 3 discrete outputs (240 VAC and 48 VDC, relay/sinking/sourcing), including one Form C (SPDT) relay.","Discrete output load current: 3 A/point relay, 50 mA/point discrete.","Integrated dynamic braking is included; there is no integrated EMI filter and the drive is not internally bypassed.","Mounting is panel or wall with spring clamp terminals; programming language is ladder.","Optional EtherNet/IP and Modbus TCP card available; EtherNet/IP is not provided on the drive itself.","Intended for 3-phase induction and permanent magnet AC motors."],"safety_notes":["Safe Torque Off (STO) is built in.","UL Listed, File # E198015.","RoHS status: Yes (see CE declaration).","CE declarations are available; CSA File # is none.","A user-supplied external fuse is required."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/general_purpose_vfds/gs21-22p0","title":"DURApulse AC General Purpose Drive: 230 VAC, 2hp with 1-phase input, (VFD) (PN# GS21-22P0) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS21-22P0_cutsheet.pdf","title":"GS21 22P0 cutsheet","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":10,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"vfd","manufacturer":"automationdirect","controllers":[],"weight_kg":1.5195,"supply_voltage":"230 VAC","rated_power_kw":1.4914,"frame_size":"C","ip_rating":"IP20","operating_temp_min_c":-20,"operating_temp_max_c":50,"joints":[],"protocols":["modbus-rtu","modbus-ascii"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/automationdirect-gs21-22p0","license":"https://creativecommons.org/licenses/by/4.0/"}
