The Altronic DSG -1201 series is an advanced digital/bargraph setpoint gauge for monitoring and displaying speed or rate. The device can be used to monitor speeds of engines or other rotating equipment. The input pulse rate can originate from a C.D. ignition system, magnetic pick-up or other type of active pick-up varying from 0.5 to 500 pulses per revolution. The speed display can be at any designated ratio to the measured RPM. Power requirement is 12-36Vdc, 50mA maximum. The front panel of the microprocessor-based gauge has a sealed membrane keypad for easy selection or adjustment of the input pulse count, speed ratio, decimal point and setpoints. The DSG-1201 models have four setpoints with individual solid state outputs which can be programmed for either high or low, N.O. or N.C. operation. In addition, each setpoint is individually adjustable for hysteresis, trip delay time and reset delay time. The precise, programmable nature of the output switch operation allows these gauges to be used as control devices. A unique feature of the DSG series gauges is the digital readout/ bar-graph display. The analog bar-graph gives the operator an immediate indication of the reading as a percent of (user selectable) RPM span or span between high/low setpoints, as well as a reference to direction and amplitude of a rapid change in reading. The display also indicates “RPM” (which can be turned off for other rate applications) and annunciates alarms by number. The optional DSG-1201 DUP model offers a 4-20mA output option which is user-programmable from the front keypad. This feature can be used for feedback to a computer control system for process control or directly to an Altronic CPU or DISN ignition system for timing control.
