Frequency meter and totaliser with additional functions and external power supply for installation in control panels.
The PMX400 series offers high-quality 4-character LED displays in 1/8 DIN format with additional functions. A variety of frequency signals can be processed with the displays. On the output side, optional analogue signals are available, as well as either two or four relay contacts for limit-value monitoring.
The programmable meter components from the PTX800 series with 8-bit digital display: capable of processing input-side TTL signals or optional pulses from NAMUR and NPN/PNP sensors. Comprehensive linearisation and interference-suppression functions are available for processing measurement signals. An mA/V analogue signal and two CO contacts for limit-value monitoring are optionally available on the output side.
Both counters feature 24-VDC voltage for supplying external two-wire sensors.
Signal converter/insulator, Configurable for 4 ranges , 0...20 mA or 0...11 V
