Application
The 5725 measures, scales, and displays frequency signals found in many process speed and flow rate applications.
The indicator can measure the period of the frequency, useful for displaying the elapsed time between events.
The 5725D has two SPDT setpoint contacts and a 0/4...20 mA output for process control.
The installed display provides IP65 environmental sealing, and additional protection is provided by the optional 8335 splash proof cover.
Technical characteristics
4-digit display with 13.8 mm high, 14-segment LED digits and adjustable decimal point.
Indicator is scalable from -1999 to 9999.
Scrolling help text makes programming easy.
Customizable trigger levels allow measurement of nearly any pulse sensor.
Built-in excitation source for measuring NPN, PNP, NAMUR and S0 sensors.
Fast response time of 1 cycle + 100 ms, and excellent accuracy of better than 0.05% of selected range.
The analog output current on the 5725D can be dampened from 0.1 to 60 seconds, and can handle up to 800 Ohms loop load.
The 5725 meets NAMUR NE21 recommendations for high performance in harsh EMC environments.
2.3 kVAC galvanic isolation between input, output and supply.
Excellent signal/noise ratio of > 60dB.
