Bargraph display MB2 Frequency

MB2 LED meter bargraph meter for frequency metering

Item description

The MB2-1FR5B.0307.S72AD is a 5-digit display with a 270° bargraph for measuring of pulses via incremental encoder, NPN-/PNP- or Namur-sensors and visual limit value monito- ring via the display. The configuration happens via 4 front keys or via an optional PC-software. The device is equipped with two switching outputs and one integrated direct voltage output serves as supply for possible sensors. Optional available are one analog output, interfaces RS232/RS485 and one pulse input. Selectable software functions and the direct limit value adjustment in operating mode complete the modern device concept.
