FM Series - Digital Measure Counters

FM Series Digital Measure Counters

The FM series measure counters can preset multiple or divisor for 1 input pulse and display the calculated value in multiply-mode and divide-modes. The counters feature counting speeds of 1 cps, 30 cps, 300 cps, 2 kcps, and 5 kcps and decimal point display function (fixed decimal point). The FM series counters feature a standard DIN size of W 72 x H 72 mm and are available in 4-digit and 6-digit models.
