∗ Contact rating is reduced for units used in hazardous locations.
† 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
