  General Specifications

  Display	8 digits Red or Green LED (character height 10 mm) with zero-suppress function. Decimal Point setting is optional (front setting or external control). Over-range indication by flashing of LED at upper left of the display section.
  Counter Input	In case of ON-OFF pulse: No voltage contacts or open collector (NPN). Counts with ON. Contact capacity DC 12 V 8 mA, “H” = 9 to 12 V, “L” = 0 to 6 V In case of voltage pulse: Counts at rising from “L” to “H”. “L”=0 to 2V, “H”=4.5 to 30V Input resistance approximately 5kΩ. * In case of relay contact, take caution on counter error because of chattering.
  Maximum counting speed	10 cps / 5 kcps (by selection of input terminal).
  Min. pulse width	50ms at 10 cps, 0.1ms at 5 kcps
  Memory retention	Non-volatile memory for approximately 10 years.
