Designed for frequency to current and voltage conversion, with output programmable to show period and pulse division or multiplication and buffering of fast pulse trains, this DIN rail signal conditioner provides AC/DC Supply, 0 KH to 20 kHz I/P, Frequency I/P & Process O/P Class.
Designed for frequency to current and voltage conversion, with output programmable to show period and pulse division or multiplication and buffering of fast pulse trains, this DIN rail signal conditioner provides AC/DC Supply, 0 KH to 20 kHz I/P, Frequency I/P & Process O/P Class.
Programmable f/I - f/f converter that performs frequency to current and voltage conversion. Typical pulse sources are flow meters, tacho generators, mechanical switches, or inductive proximity sensors. The f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
