Frequency/Pulse to Process Signal Converter

• Inputs from 50 mV to 230 VAC, frequencies from 1 pulse per hour up to 100 kHz.
• Good for impeller flowmeters, rotating shaft speed measurement using proximity sensors.
• Power frequency conversion for generator monitoring and control.
• Configurable low frequency response.
• Pulse width and PWM conversion.

Specifications:

• Input signal frequency range from 0.01 Hz to 100,000 Hz.
• Standard operating ranges:
• One pulse per hour to one pulse per second 0.001 to 10 Hz, 0.01 to 100 Hz, 0.1 to 1,000 Hz, 1 to 10,000 Hz, 10 to 100,000 Hz.
• Input types:
• AC - 10 V AC to 250 V AC (mains and other larger AC signals).
• AC – 50 mV AC to 10 V AC (impeller type flowmeters).
• DC offset - < 2 V to > 15 V (proximity switches, potential free contacts)
• DC offset - < 9 V to > 18 V
• DC offset – others
• Namur
• ±10% over and under-range on the input.
• Output signal range 4-20 mA, 0-20 mA, 0-10 V, 0-5 V, ±10 V.
• When input frequency goes below the “drop-out” frequency for the “drop-out” delay time the output goes to the “drop-out’ output value (all configurable).
• Output zero and span adjustable approximately ±10% of the range.
• Step response approximately 10 mSec for frequency inputs above 100 Hz and at input frequency below 100 Hz.
• Linearity better than 0.2% of full scale.
• Input LED flashes with the input (yellow) indicating that the input is detected.
• Input supply 24 VDC, 12 VDC ±10% or 22 to 30 VDC.
• Isolation between input, output and DC supply >1000 VDC.
• Operating temperature -10 to 65°C.
• Calibration sheet provided for each unit manufactured.
• DIN rail mounting.
• Screw terminal connections.
• Dimensions 25 x 80 x 85 mm (W x H x D).
