DGC-2020HD Speed Signal Inputs
6 • Speed Signal Inputs
The DGC-2020HD uses signals from the generator voltage sensing inputs, magnetic pickup (MPU) input,
or both inputs to detect machine speed.
Magnetic Pickup
Voltage supplied by a magnetic pickup is scaled and conditioned for use by the internal circuitry as a
speed signal source. The MPU input accepts a signal over the range of 3 to 35 volts peak and 32 to
10,000 hertz.
Terminals
Magnetic pickup connections are provided at terminals 106 (+) and 107 (–).
Generator Sensing Voltage
The generator voltage sensed by the DGC-2020HD is used to measure frequency and can be used to
measure machine speed.
Terminals
Sensing voltage is applied to terminals 86 (A-phase), 88 (B-phase), 90 (C-phase), and 91 (Neutral).
