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.
