AD61(S1)

High speed counter module

The high speed counter modules are designed to accept

input pulses at frequencies up to 50 kHz. Count input

pulses with rise and fall times of as little as 500

s can be

counted. The modules have a wide counting range: from 0

to 16,777,215. The counter can be preset or disabled by

external signals, as well as from the sequence program in

the host PLC CPU.

Other features such as a ring counter function and external

outputs are also available.
