Frequency panel meter 2051 series

digitalLEDpanel-mount

2051 Panelmeter for pulse sensors • Input frequency range 0,0001 Hz..5 kHz • Sensors: NPN, PNP, Namur, Closing contact or Pickup • 6-digit processor-based LED display, digit height 15 mm • Galvanically isolated output 0/4..20 mA, 0..10V • Two alarm relays • Pulse output for a cumulative counter • Serial output RS-232 or RS-485 • Sensor supply 24 VDC, max. 150 mA • Power supply 85..240VAC or 12..32 VDC/24 VAC The panelmeter 2051 is designed for pulse sensors, whose frequency will be measured. The inputs are NPN-, PNP-, Namur -sensors, closing contact or a pickup-sensor. The input frequency range 0,0001Hz .. 5 kHz is exceptionally wide starting with extremely low frequencies. The display is scaleable on the whole frequency range, e.g. 0-1,23 Hz can correspond to the range 0-5000 on the display . Output is freely scaleable on the basis of the display, e.g. 4-20 mA. The measuring method applied for low frequencies is to measure the time interval between two incoming pulses and for higher frequencies to measure the frequency. The display also provides a power supply of 24VDC, max. 150 mA for a sensor. The panelmeter has two optional card slots: one for output 0/ 4-20 mA, 0-10V, and the other for alarms or serial output RS485/232. Optional cards can easily be added on afterwards as well.
