Frequency and Pulse Modules

The 4222 is a universal current/voltage to frequency converter. The 4222 accepts RTD, TC, Ohm, potentiometer, mA and V inputs and produces a frequency output between 0.001 and 25,000 Hz. The unit can be programmed via the detachable 4501 display front.

The 4225 is a universal frequency to current/voltage tor frequency to frequency converter. The 4225 accepts a frequency input between 0 and 100kHz and produces an active and passive current output ±23mA, Voltage output ±10vDC or a digital NPN/PNP output. The unit can be programmed via the detachable 450 series programmable interfaces.
