{"id":"automationdirect-gs4-2015","model_id":"GS4-2015","name":"AutomationDirect GS4-2015","summary":"The GS4-2015 is a DURApulse GS4 series AC variable frequency drive sold by AutomationDirect. It accepts 230 VAC input and provides a 3-phase PWM output for controlling 3-phase induction motors using SVC or V/Hz mode. It includes an RS-485 port, integrated dynamic braking, and built-in Safe Torque Off (STO).","study_notes":["Input ratings: 15 hp with 3-phase input and 5 hp with 1-phase input. Current ratings: 47 A with 3-phase input and 17 A with 1-phase input; variable torque rating is 49 A.","Control mode is SVC or V/Hz. Output frequency range is 0.1–599 Hz; carrier frequency range is 2–15 kHz.","Native RS-485 (RJ12) protocols are Modbus RTU, Modbus ASCII, and BACnet; port speed is up to 115.2k baud. BACnet has no matching protocol id in this schema.","Optional EtherNet/IP and Modbus TCP cards are available; these are not native ports.","Three analog input channels accept 0–20 mA, 4–20 mA, or ±10 VDC with 11-bit resolution.","Two analog output channels provide 0–20 mA, 4–20 mA, or 0–10 VDC with 10-bit resolution.","Eight discrete inputs are rated 24 VDC and are sinking/sourcing. Four discrete outputs are relay/sinking/sourcing, including two Form C (SPDT) relays.","Discrete output nominal voltage is 240 VAC and 48 VDC. Relay load current is 3 A/point; discrete load current is 50 mA/point.","Integrated dynamic braking and built-in reverse capability. Programming language is ladder.","For use with 3-phase induction motors. Mounting is panel or wall.","Input signal can be 4–20 mA, voltage, or potentiometer input."],"safety_notes":["Built-in Safe Torque Off (STO).","UL Listed File # E198015.","Operating temperature range: -10 to +50 °C.","Requires a user-supplied external fuse.","CE declaration available; RoHS compliant.","NEMA 1 enclosure."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/high-performance_vfds/gs4-2015","title":"DURApulse AC High-performance Drive: 230 VAC, 15hp with 3-phase input, 5hp with 1-phase input, (VFD) (PN# GS4-2015) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS4-2015_cutsheet.pdf","title":"GS4 2015 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":6.849244787,"supply_voltage":"230 VAC","frame_size":"B","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-gs4-2015","license":"https://creativecommons.org/licenses/by/4.0/"}
