Datexel Signal Converter Dual RTD Input, Analog Output - DAT2166

Programmable Zero & Span, EMC compliant – CE mark, Watch-Dog Alarm, DIN rail mounting - Great Quality

The double channel converter DAT 2166 is designed to provide on the output two linearized voltage or current signals proportional with the temperature characteristics of the Pt100 sensors connected on its inputs. It is possible to connect on the input both 3 wire Pt100 and 2 wire Pt100.

The user can program the input ranges and the output signal type of each channel by the proper DIP-switches available after opening the suitable door located on the side of device.

The regulation of Zero and Span values is made by the ZERO and SPAN potentiometers located on the front side of device.

Moreover, an isolation of 1000 Vac is provided among the channels; it allows to avoid signal errors due to the ground loops and to reduce eventual R.F. Interferences.

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