SD340: Dual Frequency Meter 6 digit

SKU: sd340-dual-frequency-meter-6-digit Category:


The SD340 is a universal programmable frequency display with 2 encoder inputs for the selective speed monitoring, lead times as well as speed ratios or rotational speed differences. The numerous adjustable operating modes such as tachometers, speed measuring devices or timers of this mounted devices ensure flexible application possibilities for a wide range of requirements in machine and plant engineering. The integrated serial RS232 interface can be operated in the PC or printer mode.

The SD340 device easily handles high input frequencies up to 1 MHz and also has 4 programmable limit values which enable a switching function via 4 fast transistor outputs.





  • 2 scalable inputs with format A, /A, B, /B
