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.
