Digital indicator M2 Frequency

Digital indicators for frequency measurement and pulse measurement.

Item description

The M2-1FR5B.0307.570CD is a 5-digit meter for measuring of pulses via incremental enco- der, NPN-/PNP- or Namur-sensors and a visual limit value monitoring via the display. The con- figuration happens via four front keys or via an optional PC-software. For further evaluation, options like one analog output, one digital in- put, one pulse input and 2 switching points are available. Selectable software functions, a direct limit value adjustment in operating mode and the compact installation depth of 89mm create a solid device concept.

Digital indicator M3 Frequency

LED indicators for frequncy measurement.

Item description

The M3-1FR5B.0307.S70BD is a 5-digit meter for measuring pulses via incremental enco- der, NPN/PNP- or Namur sensor and a visual limit value monitoring via the display. Configu- ration happens via four front keys or via an optional PC-software. Optional 2 analog out- puts, interfaces RS232/RS485 and up to 8 switching points are available. Selectable software functions and a direct limit value adjustment in operating mode complete the modern device concept.
