The Dart DM8000 is a multi-purpose display capable of not only typical rate/time in process/percent actual speed display, but also may be configured as a counter/totalizer and even a zero speed switch. An encoder is required to monitor shaft speed (see the Dart PU Series). The display can actually be shared between two inputs, saving panel space and cost. Alarm / total count relay outputs are standard. Supply voltage is 120/240VAC. Standard 1/8 DIN panel mount.
