1-6 DGC-2020 General Information 9400200990 Rev IOutput 5: 57, 55 (common)Output 6: 58, 55 (common)Output 7: 60, 59 (common)Output 8: 61, 59 (common)Output 9: 62, 59 (common)Output 10: 64, 63 (common)Output 11: 65, 63 (common)Output 12: 66, 63 (common)∗ Contact rating is reduced to 3 A for part numbers 9400200105 and 9400200106 when used in ahazardous location.† The number of programmable output contacts provided is determined by the output contactscharacter of the DGC-2020 style number. Controllers with output contacts option A have 4 program-mable outputs (Outputs 1, 2, 3, and 4). Controllers with output contacts option B have 12programmable outputs.The programmable relays share common terminals: terminal 51 is used for outputs 1, 2, and 3,terminal 55 is used for outputs 4, 5, and 6, terminal 59 is used for outputs 7, 8, and 9, 63 is used foroutputs 10, 11, and 12.MeteringGenerator Voltage (rms)Metering Range: 0 to 576 Vac (direct measurement)577 to 9,999 Vac (through VT using VT ratio setting)VT Ratio Range: 1:1 to 125:1 in primary increments of 1Accuracy: ∗ ±1.0% of programmed rated voltage or ±2 VacDisplay Resolution: 1 Vac∗ Voltage metering indicates 0 V when generator voltage is below 2% of the full-scale rating.Generator Current (rms)Generator current is measured at the secondary windings of user-supplied 1 A or 5 A CTs.Metering Range: 0 to 5,000 AacCT Primary Range: 1 to 5,000 Aac in primary increments of 1 AacAccuracy: ∗ ±1.0% of programmed rated current or ±2 AacDisplay Resolution: 1 Aac∗ Current metering indicates 0 A when generator current is below 2% of the full-scale rating.Generator FrequencyGenerator frequency is sensed through the generator voltage input.Metering Range: 10 to 72 Hz (50/60 Hz)10 to 480 (400 Hz)Accuracy: ±0.25% or 0.05 HzDisplay Resolution: 0.1 HzApparent PowerIndicates total kVA and individual line kVA (4-wire, line-to-neutral or 3-wire, line-to-line).Measurement/Calculation MethodsTotal: kVA = (VL-L × IL ×√3) ÷ 10004-Wire, Line-to-Neutral: kVA calculated with respect to neutral3-Wire, Line-to-Line: A-phase kVA = V AB × IA ÷ 1000 ÷ √3B-phase kVA = V BC × IB ÷ 1000 ÷ √3C-phase kVA = VCA × IC ÷ 1000 ÷ √3Accuracy: ±3% or the full-scale indication or ±2 kVA ∗†∗ kVA metering indicates 0 kVA when the generator kVA is below 2% of the full-scale rating.† Applies when temperature is between -40°C to +70°C.www .
