The TWN-FF & TWI-FF are designed as an interface between a Trimec IF500 (was DP490) Flow Transducer and a PLC. The TWN-FF & TWI-FF divide the frequency of the pulses from a IF500 to an output frequency a PLC can Register without missing counts. For example if a IF500 is measuring flow that results in an output frequency of 40Hz, and the maximum PLC input frequency is 10Hz, the TWN-FF & TWI-FF would be ordered with a division factor of four.
The TWN-FF & TWI-FF can be powered by the PLC's 24Vdc power supply. The output is a 50:50 mark space ratio, and can be directly connected into most PLC digital inputs.
