Description
The HSPZA22SL is a factory programmed module available
in any 1 of 13 standard functions. The HSPZA22SL offers dual
switch adjustable timer or counter functions. Switch adjustment
allows accurate selection of the time delay or number of counts
the first time and every time. The 1A steady, 10A inrush rated
solid-state output provides 100 million operations, typical. Its
microcontroller timing circuit provides excellent repeat accuracy
and stability. Encapsulation protects against shock, vibration,
and humidity. The HSPZA22SL is a cost effective approach for
OEM applications that require small size, solid state reliability,
and accurate switch adjustment.
Operation (Single Shot Lockout)
Upon application of input voltage and momentary or maintained
closure of S1, the output relay energizes and TD1 single shot
time delay begins. The output relay de-energizes at the end of
TD1 and the TD2 lockout time delay begins. During TD2 (and
TD1) closing switch S1 has no effect on the operation. After TD2
is complete, closing S1 starts another operation. If S1 is closed
when input voltage is applied, the output energizes and the TD1
time delay begins.
Reset: Removing input voltage resets the time delays and the
output and returns the cycle to the first delay.
