Application

• The f/I function performs frequency to current and voltage conversion. The output can be programmed to show period, meaning that the input frequency can be converted to a linear time signal. The digital outputs are used as e.g. a frequency watch for speed control or as a window comparator having one status between 2 limits and the opposite status outside these limits.
• The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains. The input pulses are calculated, counted in a buffer, and sent to the output as a pulse train with the programmed pulse width. A scale factor may be entered in all functions. Using both digital inputs, pulse addition or subtraction are possible. This function permits readout of the actual consumption at measurement of e.g. liquid flows forward and reverse.
• The frequency generator function is used as e.g. a time base or clock generator
• The 2-phase encoder, or directional f/I conversion, converts 2 90°- phased digital inputs to an analogue speed signal with digital output for directional indication.
• ATEX units have input for mechanical contact and Namur inductive proximity sensor.
