Product Details

Description

The TWN-FF & TWI-FF are designed as an interface between a Flomec DP490 Flow Transducer and a PLC. The TWN-FF & TWI-FF divide the frequency of the pulses from a DP490 to an output frequency a PLC can Register without missing counts.

For example, if a DP490 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.

TWI-FF \ TWN-FF Features

  • Frequency I/P divided to a frequency output
  • LED indication of frequency output
  • Isolated input to output 1.6kV for TWI-FF
  • Easy to install
  • Compact DIN rail mount enclosure
  • Reverse polarity protection
  • Externally accessible span and zero adjustments
