Product Description:

The SQC12000 Counter by Danaher supports a count rate of 2.4 kHz, which allows it to process high-speed pulses precisely for challenging automation applications. This counter comes with several count modes, such as a/s (add/subtract) and quad, which allow both unidirectional and bidirectional input signals across different control systems.

An advanced anti-coincidence feature of this counter is implemented in the add/subtract mode, which provides precise pulse differentiation and removes overlap between input signals during high-frequency counts. This counter boasts a transflective LCD display that is easily readable even in direct illumination, while a backlit LED guarantees complete readability under low industrial lighting conditions. This counter’s input calibrator offers an accurate adjustment range from 0.0001 to X.XXXX to ensure detailed setting of input pulse scaling to suit application-specific needs. The output time of the SQC12000 is completely programmable between 0.01 to 99.99 seconds, and it has both momentary and latch output modes to drive external devices in terms of pulse duration requirements. There are three reset types of this counter, namely push-button reset with enable selection, remote reset, and auto reset, which offer flexible reset methods for different operating work patterns.

This counter comes with a power supply of 85 to 260 VAC at 50/60 Hz, and can handle a maximum power consumption of 6 VA to make it adaptable to global industrial voltage systems. This counter has a panel cutout of 45 mm x 45 mm, and for safe and easy wiring, this counter employs pluggable screw terminals that ensure solid electrical connections and easy maintenance processes. The front panel of this counter is sealed to comply with NEMA 4X/IP65 protection standards to offer high resistance against dust entry and water spray. The operating temperature range of SQC12000 counter is defined between 32 °F and 122 °F (0 °C and 50 °C) for consistent performance within moderately cold and warm working conditions in dissimilar industrial locations.

Frequently Asked Questions about SQC12000:

Q: Why is the LED backlight important for the SQC12000’s LCD display?

A: It improves visibility in poorly lit areas and supports constant readability in control panels. This is particularly useful in dim factory or field conditions.

Q: How does the anti-coincidence feature benefit the SQC12000 during counting?

A: It prevents simultaneous signal overlap, improving pulse accuracy during high-speed dual-channel counting. This ensures more reliable readings in fast or noisy environments.

Q: How does the SQC12000 handle noisy electrical environments?

A: Its pluggable screw terminals provide secure and stable connections, reducing the risk of signal interference. This ensures cleaner pulse processing and data accuracy.

Q: What is the purpose of the adjustable calibrator in the SQC12000?

A: It allows the input pulses to be scaled based on user requirements. This is helpful when aligning pulse data with external process variables or units.

Q: Why does the SQC12000 support multiple reset modes?

A: It allows users to choose manual, remote, or automated reset depending on workflow. This flexibility helps maintain process control under varying operational scenarios.
