** SIGNAL ** The DB1-128 is a general purpose module designed to work with most standard automotive or diesel speedo’s and tachometers as used in marine, automotive, and commercial vehicles, tractors, generator sets, etc. These are usually driven by a magnetic pickup, alternator AC connection or electronic ignition auxiliary signal. This unit will take the weaker signals often received from these systems and boost them to a 12v p-p square wave suitable for most inputs. The signal may also be reduced in frequency by a factor of 1, 2, 4, 8, 16, 32, 64 or 128 so as to allow easier adjustment of the driven instrument.
