Introduction
The Daniel Digital Rate Internal Display is an explosion-proof pulse input rate/ display fully
featured for demanding applications in hazardous areas or in the harshest environmental
conditions. It can be programmed using the four through-glass buttons, without
removing the cover, or with four internal push-buttons.
The numeric rate display reads up to five digits and the alphanumeric total/tag display
reads up to 7 digits. The total overflow feature reads up to 12 digits. The alphanumeric
display can also be programmed to display any combination of numbers and letters up to
seven characters long for use as engineering units and/or the process identification tag.
The backlight increases the visibility of the display under various lighting conditions. The
