Dual Channel RTD Pt100 Temperature converter DAT2166

General Description

The Dual Channel Pt100 Temperature converter DAT2166 is a DIN Rail mount temperature converter with DIP Switch programmability and is designed to accept and transmit two separate channels. The output can be voltage or current.
The DAT2166 is accurate to 0.1% full scale and has less than 0.02%/°f thermal drift.
It is possible to set the coarse range and zero with the DIP switches. Use the potentiometers to fine tune the output whilst keeping within the minimum and maximum ranges shown in the table on the data sheet. The potentiometers are located on top of the DAT2166.
The DAT2166 accepts both 2 wires and 3 wire RTD's.
The DAT2166 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT2166 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.
The DAT2166 is isolated between the two channels to 1000V and eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.
