5 KHz when driven by bi-polar outputs or external circuits having an output
impedance of 3.3 KΩ or less. Input drive voltage must be limited to 3 V
maximum to avoid damage to the counter. CMOS and TTL logic outputs can
be loaded with a resistor (Rl) to limit drive voltage, or a voltage divider can
be used as shown for the PNP O.C. transistor output.
RESET OPTIONS
Common will enable the front panel Reset button. When Remote Reset is
required, a wire is connected from the “REM. RST.” input terminal to
Common. Pulling this input low causes the counter to reset. The “REM. RST.”
can be pulled low by either a mechanical switch or solid-state transistor
switch. Switch load and leakage are the same as for “L.S. CNT.” Input above.
Note: The RC protection circuit on the “REM. RST.” Input causes a delay of
CUB4L8 HIGH SPEED COUNT INPUT, 5 Hz MAX.
The “H.S. CNT.” Input allows the CUB Counter to operate at speeds up to
Connecting a wire from the “RST. EN.” (Reset Enable) Input terminal to
approximately 15 msec in Reset response.

signal is connected to Terminal 1 (COM), and line (hot) is
connected to Terminal 5 (LS). The DC supply for the backlighting
is connected as shown in the drawing. Three phase AC applications
require an isolation transformer.
