Datexel Frequency Converter Trip Amplifier with Relay Output - DAT4540 R

Double optional trip alarm, Configurable by Dip-switch or PC, Galvanic insulation, EMC compliant – CE mark - High Quality

The isolated frequency converter DAT 4540 is able to measure, up to 20 KHz, the frequency of TTL, Namur, NPN, PNP and Tachometer digital signals.

In function of programming, the measured values are converted in a current or voltage signal.

Moreover, two relays are available in order to be programmed as trip alarm (version “-R”). For the Namur input is continuously checked the integrity of the sensor; in case of fault (short circuit or interruption), on the transistor output is generated an alarm.

The device guarantees high accuracy and performances stability both versus time and temperature.

The programming is made by the dip-switch located in the window on the side of the enclosure. By means of dip-switches it is possible to select the input type and range and the output type without recalibrate the device.

By PC, the user can program all the parameters of the devices for his own necessities.

The galvanic isolation on all ways (input, outputs and power supply) eliminates the effects of all ground loops eventually existing and allows the use of the converter in heavy environmental conditions found in industrial applications.

It is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
