The IUC-79-FTF is a Frequency to Frequency Isolator that is easily field configurable to one of many input types such as several voltages or dry contact. Four standard outputs are available (open collector, TTL, 12 VDC, 24 VDC) which can be used individually or simultaneously. Discrete ON and OFF threshold adjustments allow for easy & accurate input signal conditioning. Adjustable response times allow for appropriate signal filtering.

The IUC-79-FTF-BUF is similar to the -FTF but has a microprocesser that can store incoming pulses in a buffer and release them slowly to a slower counting device.

The IUC-79-FTF-DIV is another variation of the -FTF and has the capability to divide the incoming frequency by any number between 1 and 65535
