Junior-D / Junior20-D

COUNTER, FREQUENCYMETER, PULSE INPUT

JUNIOR-D

DIGITAL PANEL METER for the following input signals:

- HIGH VOLTAGE (10 to 600V AC)
- SENSORS: MAGNETIC, NAMUR, NPN and PNP
- TTL/24V ENCODER
- CONTACT SWITCH

JR-D and JR20-D models, accept most commonly used pulse generators or transducers to work as an unidirectional counter, tachometer or frequency meter (rpm or rate).

They have configurable factor and offset when are programmed as a counter or easily scalables into desired engineering units working as tachometer or frequency meter.

Universal AC/DC voltage supply.

Fully configurables through 3 frontal keys, they allow signal input type selection and also provide 8V or 24V DC up to 60mA or 30mA load current output respectively for sensor excitation.

  • 4 digit indicator with 14mm digit and −9999 to 9999 display range for JR-D
  • 4 digit indicator with 20mm digit and −1999 to 9999 display range for JR20-D
  • Configurable decimal point for JR-D and JR20-D

Three frontal keys for configuration and 2 led for setpoints status indication (if output 2RE option card is installed).

2RE option activates two alarms depending on display programmed values, though not from totalizer which this is only an informative reading.

Configured as a counter has a totalizer (up to 999999) and a RESET function, available through frontal key or remotely. Besides current counting display, the totalizer brings the possibility of visualizing the cumulative number (divided in two parts) of pulses produced in multiple processes. Remote RESET is activated through contact switch input present at input rear connector.
When configured as a frequency meter or tachometer it is also possible to adjust internal sampling time and time limit, thus providing specific application adaptation.

Detection, saving, later recalling and resetting of maximum and minimum values reached by display since last reset activation (functions not available for counter mode).
