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.
