PR Electronics Universal f/I-f/f converter Series Frequency / Current Converter, Current, Frequency Input, Relay Output

The PR Electronics universal f/I-f/f converter with 2 relay outputs is a front programmable device. It measures frequencies up to 100 kHz. It has universal power supply 21.6 to 253 VAC / 19.2 to 300 VDC and active and passive current output of ±23 mA / 23 mA. All terminals are over-voltage protected, polarity protected and short-circuit protected. Input is NAMUR, NPN, PNP, tacho, TTL & S0 and output is programmable bipolar mA / V, frequency or relay. Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail even at 60°C ambient temperature.
