C628 Series- 1/8 DIN Electronic 1 or 2 Presets

Reset Timers, Elapsed Time Meters
C628 Versatile Digital Counter, Totalizer, batch, rate meter and lapsed time meter


  • 0.71” high digit LED display (27% larger than other 1/8 DIN units)
  • Programmable color change display based on an event
  • Batch units – Independent display of background total
  • Programmable help function and secondary legend display
  • Dual preset units – Preset 1 programmable as absolute value or prewarn which tracks Preset 2
  • Choice of NPN or PNP primary input
  • Filter speed settable for 20, 200, or 10,000 Hz
  • Standard Outputs: 1 NPN transistor (2 NPN transistors on Dual & Batch units) & 1 relay (optional 2nd relay on Dual & Batch units)
  • Front panel reset enable and preset lockout
  • Optional RS-485 plug in card
  • CE approved, UL, CUL recognized


The Veeder-Root, C628 Elapsed Timer has a definable set value at which an output will activate. The unit can be programmed to operate in a cumulative (elapsed time continues to accumulate during all instances when the input is active) or single (time value will display the elapsed time of an individual input and will reset to zero for each successive new pulse) input function mode. In addition, the time format (seconds, minutes, hours, minutes & seconds, or hours & minutes) and timing direction (up or down) can be selected.
