JR/JR20-D digital meters accept inputs from high voltage (10 V – 600 V AC) signals, contact switch signals, TTL/24V encoder inputs, and sensors of the magnetic, PNP, NPN and NAMUR type.
These models can accept all commonly used transducers or pulse generators to work as frequency meters, tachometers or unidirectional counters. They have the offset and configurable factor when programmed as a counter and they are easily scalable for use as frequency meters or tachometers.
These devices are can be configured completely with the three frontal keys. These let you select signal input type and they provide 60 mA or 30 mA, 8 V or 24 V current outputs to activate the sensors.
The JR-D has a 4 digit indicator with 14 mm digits and a display range from 9999 to 9999. The JR20-D model has also a 4 digit indicator but with 20 mm digits and the display range is from 1999 to 9999.
