Contact rating is reduced to 3 A for part numbers 9400200105 and 9400200106 when used in a
hazardous location.
† The number of programmable output contacts provided is determined by the output contacts
character 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 12
programmable 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 for
outputs 10, 11, and 12.
Metering
Generator 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 1
Accuracy:
1.0% of programmed rated voltage or 2 Vac
Display 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 Aac
CT Primary Range:
1 to 5,000 Aac in primary increments of 1 Aac
Accuracy:
1.0% of programmed rated current or 2 Aac
Display Resolution:
1 Aac
Current metering indicates 0 A when generator current is below 2% of the full-scale rating.
Generator Frequency
Generator 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 Hz
Display Resolution:
0.1 Hz
