Digital indicator M3 Frequency 96 x 24 mm

Montwill Produkte: Digital indicator M3 Frequency 96 x 24 mm

Item description

The M3-3FR5B.0307.W70xD is a 5-digit pabel meter for pulse measuring via incremental encoder, NPN/PNP or Namur sensor and a visual limit value monitoring via the display. Configuration happens via three front keys or via an optional PC-software. As options one analog output, one frequency output, the interfaces RS232/RS485 and two switching points are available. Many selectable software functions and a direct limit value adjustment in operating mode complete the modern device concept.
