{"id":"automationdirect-gs33-4100","model_id":"GS33-4100","name":"AutomationDirect GS33-4100","summary":"The GS33-4100 is an enclosed DURApulse GS30 series AC variable frequency drive rated for 100 hp on a 460 VAC three-phase input. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes, with an RS-485 port running Modbus RTU or Modbus ASCII slave protocols plus a USB B port. It mounts on a panel or wall, uses spring clamp terminals, and accepts optional communication, encoder and I/O modules.","study_notes":["Series GS30, controller type high-performance; frame size I.","Control modes: SVC, V/Hz, FOC, encoder or torque.","Amperage rating 150 A; variable torque amperage rating 180 A.","Carrier frequency range 2-15 kHz; output frequency range 0.1-599 Hz.","Discrete I/O: 7 sinking/sourcing inputs at 24 VDC, 3 relay/sinking/sourcing outputs rated 240 VAC and 30 VDC, one Form C (SPDT) relay; load current 3 A/point relay, 50 mA/point discrete.","Analog I/O: 2 current/voltage inputs, 12-bit resolution, 0-20 mA and 4-20 mA or +/-10 VDC; 1 current/voltage output, 10-bit resolution, 0-20 mA and 4-20 mA or 0-10 VDC.","Communications: (1) RS-485 (RJ45) and (1) USB B; port speed up to 115.2k baud.","Input signal options: 4-20 mA, voltage, potentiometer or pulse train input.","Programming language ladder (embedded PLC software GSLOGIC and GSOFT2 configuration software are listed).","Integrated EMI filter: no.
