Frequency Indicator

The frequency indicator is used to display AC parameters. The frequency indicator can measure and display AC current, AC voltage or frequencies. The possibility of freely scaling the input signal allows a very versatile use of this frequency indicator.

The frequency indicator is used for the signal processing of 4 .. 20 mA. The frequency indicator has a 5-digit LED display to allow the user to read the directly measured current values.

• Power supply: 230 V, 110 V, 24 V, 20 … 40 V AC/DC, 85 … 253 V AC/DC (selectable)
• Input signal: 0/4 … 20 mA, 0 … 60 mV, ±60 mV DC, 0 … 10 V, ± 10 V DC (selectable)
• Display: 4 digits, red
• Digit height: 20 mm

The frequency indicator is used for processing 4…20 mA and 0…20 mA signals. Many measuring transducers and sensors use this type of output, which makes the frequency indicator suitable in a wide application area. The measurement results are shown on the large 5-digit LED-display of the frequency indicator.

• Input (selectable): 0…20 mA, 4…20 mA, ± 20 mA
• Accuracy: ± (0.2 % FS + 1 dgt.)
• Two open collector outputs
• 24 V power supply sytem for sensors and transducers

PCE-N20U is a frequency indicator used for signal processing. Designed for quick and easy system integration, the digital panel meter features a large 5-digit LED display with tricolor coding dependent on the measured values. The PCE-N20U also can output signals via two open collector outputs when a threshold value is exceeded.

• Input (selectable): 0…10 V / 0…60 mV / ±10 V
• Accuracy: ± (0.2 % FS + 1 digit)
• 24 V power supply system for sensors and transducers

The frequency indicator can process several different input signals, such as 0…410/4010 Ohm, -10…+63 mV DC, -13…+13 V DC, -24…+24 mA DC or signals from thermocouples and resistance thermometers. This makes the frequency indicator applicable in a wide range of applications. The measured values are shown on the large LED display of the frequency indicator.
