Frequency converter DAT4540T

General Description

The Frequency converter DAT4540T is a signal conditioning din rail mount converter which converts a pulse input to an analog output equal to the set range which is selectable from 0.1 Hz up to 20 KHz. The DAT4540T also has transistor output which can be used for alarms or Pulse shaping. The input can be from a Tacho, TTL, PNP transistor or from any Namur standard. The DAT4540T provides a Voltage or Current output that is isolated from the power supply and input.
