เครื่องนับจำนวนแบบดิจิตอล Digital Counter
รุ่น 571 Series
คุณลักษณะ
The multifunction preset counter 571 with its max. 100 kHz count frequency is ideal for fast counting tasks.
It can also be used as a tachometer, short time meter, stop-watch or to measure machine cycle times or throughput times.
Versions are available with 2 alarm outputs, analogue output or with serial interface.
This device is thus able to carry out virtually all count, measurement and control tasks.
- Fast count input, works with our Limes measuring system (100 kHz).
- Version with 2 optocoupler outputs for alarms.
- Version with scalable analogue output, resolution 14 bit, 0 ... 10 V, +10 ... -10 V, 0 ... 20 mA or 4 ... 20 mA.
- Version with serial interface RS232/485 for importing and exporting data.
- Sensor power supply 24 V DC, 150 mA.
- 96 x 48 mm DIN housing, IP65.
- AC and DC power supply in one unit.
- Measuring function can be programmed for RPM, speed (from elapsed time), machine cycle time, throughput and baking time (time interval), as well as numerous count and stop-watch functions.
- Version with 2 optocoupler outputs; preset 2 can also be programmed as a tracking preset.
- Scaleable display, programmed via 2 keys.
- Large 15 mm high LED display, 6-digit, with adjustable brightness.
