General Description

The DAT2065 RTD Temperature Transmitter is a compact, DIN rail mount, loop-powered device designed for converting Pt100 RTD signals to a 4-20 mA output. It features easy DIP switch programming for setting coarse temperature ranges and offers zero and span fine-tuning via front-panel potentiometers.

Compatible with both 2-wire and 3-wire Pt100 RTDs, the DAT2065 ensures accurate signal conversion with 0.1% full scale accuracy and thermal drift below 0.02%/°F. The device includes built-in EMC protection per 89/336/CEE and is housed in a slim 12.5 mm enclosure suitable for EN-50022 / EN-50035 DIN rail mounting.

Ideal for OEMs and system integrators, the DAT2065 provides a reliable, cost-effective solution for Pt100 temperature measurement in industrial environments requiring a simple, loop-powered current output.

Frequently Asked Questions – DAT2065

What type of RTD does the DAT2065 support?
The DAT2065 supports Pt100 RTD sensors in 2-wire and 3-wire configurations.
What kind of output does it provide?
It provides a 4-20 mA current output that is temperature-linearized based on the configured range.
How is the temperature range configured?
The temperature span is set via DIP switches on the side, and zero/span fine-tuning is done via potentiometers on the front panel.
Is the DAT2065 loop-powered?
Yes, the device is loop-powered and requires no separate power supply beyond the 2-wire current loop.
Does the DAT2065 provide galvanic isolation?
No, the DAT2065 is not isolated. For isolation, consider the DAT4531B or DAT4532B series.
What is the accuracy of the device?
The transmitter is accurate to ±0.1% full scale with thermal drift less than 0.02%/°F.
