DC current/voltage to frequency isolator/converter
Module for conversion of a current or voltage analogue signal into a frequency (pulses) directly proportional to the signal applied. Widely used as an "integrator" for totalizing, with a pulse counter, flow rate signals generated by meters with analogue output signal.
INPUT: programmable via dip switches for 0 - 20 mA and 4 - 20 mA current (with both active and passive connection) or for 0 - 5 Vdc, 1 - 5 Vdc, 0 - 10 Vdc and 2 - 10 Vdc voltage.
INTEGRATION CONSTANT programmable for scale end from 1 pulse every 27 minutes to 20 pulses per second.
EXTREMELY SIMPLE CALIBRATION only requiring the use of an ordinary digital tester.
Two signaling LEDs on the front panel indicate power on and output pulse. The self-extinguishing Noryl case is the width of 3 DIN modules and is designed to fit on a 35 mm mounting rail (DIN 46277).
