Product Description:
The Danaher made the DZ100A3 solid-state counter. The counter is designed for applications requiring precise and reliable counting functions. The counter is compatible with industrial automation systems due to its assurance of accuracy across various applications.
The DZ100A3 solid state counter offers 100% accuracy for all tally settings ranging from 1 to 99. The rate of counting is 600 pulses per minute. It is necessary for each pulse to have a minimum of forty milliseconds of ON and sixty milliseconds of OFF. The time allowed for the reset is fifty milliseconds. During the COUNT cycle, the pilot light will remain on to indicate that the counter is operational. The counter may operate on 120 V with a tolerance of ±10 ~15% at 50 Hz. The maximum load for relay output at 120 VAC or DC is 1.9 VA. The relay output rating can withstand a constant state current of 10 amps. The mechanical life span exceeds 20 million operations. The electrical lifespan is determined by the parameters of the load. The counter can withstand line voltage disturbances lasting 16 milliseconds or less without resetting. After supplying voltage to ports A and B, the power-on reaction time is restricted to 30 milliseconds.
The DZ100A3 solid state counter is unaffected by transient voltages of 50 microseconds at 600 V peak applied to the line input. It performs well at frequencies ranging from 10 to 1000 Hz with sinusoidal vibration magnitudes of 2.5G in both directions along three perpendicular mounting axes. The temperature range for operation is 0°C to 60°C (+32°F to +140°F). The solid state counter meets the standards for U.L. Recognition E96337 and C.S.A. Certification L26861. These features ensure that professional applications operate reliably and compliantly.
Frequently Asked Questions about DZ100A3:
Q: Why does the DZ100A3 require a 40-ms ON pulse?
A: The 40-ms ON pulse ensures the input signal is fully recognized by the counting circuit. This prevents missed counts and ensures stable counting performance.
Q: Does the DZ100A3 support multiple operating voltages for flexibility?
A: Yes, the counter operates on both 120 VAC/DC and 240 VAC/DC with ±10 ~15% tolerance. This allows integration with different electrical system requirements.
Q: Why does the DZ100A3 have a 50 ms reset time?
A: The 50 ms reset time allows the system to stabilize before starting a new cycle. This ensures correct count initialization for accurate operation.
Q: How does the DZ100A3 handle short power interruptions?
A: It withstands line voltage interruptions of up to 16 milliseconds without resetting. This prevents false resets and maintains continuous operational integrity during brief power drops.
Q: Do the relay contacts of the DZ100A3 handle high current?
A: Yes, the relay output rating supports 10 amps steady state. This allows reliable control of higher current loads without damaging the relay mechanism.
