RTD Temperature converter DAT2165.
• RTD Temperature converter.
• DIP Switch Programmable.
• DIN Rail Mounted.
General Description

The DAT2165 Pt100 Temperature Converter is a DIN rail mount signal converter designed for precise RTD measurement and flexible output options. Unlike the loop-powered DAT2065, the DAT2165 provides both current and voltage outputs, making it suitable for integration into a wider range of PLCs and control systems.

Configurable via DIP switches, the DAT2165 allows coarse range and zero adjustments, with fine-tuning available through top-mounted potentiometers. It accepts 2-wire and 3-wire Pt100 RTD sensors, ensuring compatibility in industrial temperature monitoring applications.

With 0.1% full scale accuracy and thermal drift below 0.02%/°F, the DAT2165 delivers stable and reliable signal conversion. Housed in a slim 12.5 mm DIN rail enclosure, the device complies with EN-50022 / EN-50035 mounting standards and EMC requirements (89/336/CEE).

The DAT2165 is the ideal choice when a Pt100 RTD signal needs to be converted to either voltage or current output, offering enhanced flexibility compared to loop-powered transmitters.

Frequently Asked Questions – DAT2165

What is the main difference between the DAT2165 and the DAT2065?
The DAT2065 is loop-powered and provides only a 4-20 mA current output, while the DAT2165 is externally powered and provides both current and voltage outputs.
What RTD types are supported?
The DAT2165 supports Pt100 RTDs in 2-wire and 3-wire configurations.
How is the DAT2165 configured?
The device uses DIP switches for coarse range and zero, with fine-tuning adjustments via potentiometers on the top of the module.
Does the DAT2165 provide galvanic isolation?
No, the DAT2165 is not isolated. For isolation and wider RTD compatibility, consider the DAT4531B or DAT4532B.
What is the accuracy of the DAT2165?
The converter provides 0.1% full scale accuracy with thermal drift of less than 0.02%/°F.
What standards does it comply with?
The DAT2165 complies with EMC directive 89/336/CEE and is designed for DIN rail mounting per EN-50022 and EN-50035 standards.
