Datexel Signal Conditioner Multiple Input and Output DAT 5028-4

High Accuracy, Multiple Input, Analog and Digital Output Great Quality

The DAT 5028 device is able to acquire RTD or Tc sensors, mV, V or mA input signals connected to the universal analogue input. By means of push-button and 4-digit display on the front panel, four different trip alarms are configurable.

Each alarm threshold commands an output relay. Input signal can be retransmitted on the analogue output in a Voltage or Current signal, configurable by means of dip-switch on the side of the device.

By means of an internal 16-bit converter, the device guarantees a high accuracy and a stable measure versus time and temperature.

The 1500 Vac isolation on all ways removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.

In function of the number of thresholds necessary to the user, the device can be supplied in two different versions:

DAT5028-4 with 4 thresholds (2 SPDT + 2 SPST);

DAT5028-2 con with 2 thresholds (2 SPDT).

The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5mm only, allows a high density mounting on EN-50022 standard DIN rail.
