Product Description:

The SSIV-21 represents Danaher’s latest offering in the Timers and Controllers series featuring 6 decades of counting which provides consistent enhanced resolution for comprehensive industrial event monitoring. The display comprises 12.7 mm, red LEDs which ensure optimal visibility under various lighting conditions. A maximum count speed of 1500 cpm (25 Hz) accommodates continuous moderate-rate processes to guarantee no pulse omissions.

Count impulse voltage compatibility of 105–120 VAC or 210–250 VAC allows connection to circuits and removes transformer requirements. Its minimum impulse on/off time of 0.02 s accepts rapid signals that preserves count precision. This feature of manual reset by pushbutton resets to zero allows speeds batch transitions. While a remote reset using switch/contact closure or open-collector NPN enables actuation which integrates with automation. Remote reset duration of 100 ms ensures activation reliability which prevents noise triggers. The device’s power consumption of 1.5 W reduces heat generation.

Remote reset operations of SSIV-21 require a minimum pulse duration of 100 ms which guarantees signal integrity in electrically noisy environments. This industrial unit accepts an operating supply of 105–120 VAC or 210–250 VAC with 50/60 Hz frequency which aligns with regional power infrastructures. Rated power consumption of 1.5 W limits electrical load which reduces thermal accumulation inside control cabinets. It provides 12-inch color-coded wire leads with clear polarity identification that streamlines installation and service. Specified ambient operating temperatures range from 0°C to +55°C in order to preserve functionality in standard industrial climates. The device with storage capability spans of -40°C to +74°C shields internal components from extreme temperature excursions during shipping and layup.

Frequently Asked Questions about SSIV-21:

Q: What counting resolution does the SSIV-21 provide?

A: The SSIV-21 incorporates six decades which permits six-digit counts for tracking up to 999999 events before rollover. This extended range reduces intervention frequency in long production cycles.

Q: How does the red-LED display benefit SSIV-21 operation?

A: A 12.7 mm high-intensity red-LED display maximizes readability in varied lighting conditions which accelerates visual checks and minimizes misreads during routine inspections.

Q: Why is the maximum count speed specification critical for SSIV-21 use?

A: Maximum count speed of 1 500 cpm (25 Hz) supports moderate pulse rates, ensuring the timer accurately registers events in standard automation processes without missing pulses.

Q: How does dual-range impulse voltage affect SSIV-21 installation?

A: Acceptance of 105–120 VAC or 210–250 VAC count impulses enable seamless integration with differing plant power systems which eliminates auxiliary voltage conversion equipment.

Q: What role does minimum impulse on/off time play in SSIV-21 accuracy?

A: This timer’s minimum on/off time of 20 ms prevents miscounts during fast signal transitions which upholds tally integrity in quick-cycling machinery.
