What is the output type of the DAT2045?

The DAT2045 provides a 4-20 mA output that is linear to the voltage input from the thermocouple. It is not temperature-linear.

How is the DAT2045 configured?

Configuration is done using DIP switches for coarse range and zero, and onboard potentiometers for fine-tuning the output signal.

Is the DAT2045 isolated?

No, the DAT2045 does not offer galvanic isolation between input and output. For isolated applications, consider the DAT4531A.

What accuracy does the DAT2045 offer?

It provides 0.1% full scale accuracy with less than 0.02%/°F thermal drift.

Does it have cold junction compensation?

Yes, the DAT2045 includes internal cold junction compensation for thermocouple accuracy.

What mounting and enclosure standards does it support?

The transmitter is housed in a 12.5 mm plastic enclosure suitable for DIN rail mounting per EN-50022 and EN-50035 standards.

General Description

The DAT2045 Thermocouple Transmitter is a compact DIN rail mount temperature transmitter designed for basic thermocouple applications. It features DIP switch configuration for coarse range and zero settings, and fine output adjustments using onboard potentiometers. The DAT2045 provides a voltage-linear 4-20 mA output, making it suitable for systems that handle temperature linearization externally.

Designed for cost-effective installations, the DAT2045 includes internal cold junction compensation and ensures ±0.1% full scale accuracy with thermal drift under 0.02%/°F. Housed in a slim 12.5 mm DIN rail plastic enclosure, it complies with EN-50022 / EN-50035 mounting standards and meets EMC requirements per 89/336/CEE.

Ideal for OEMs, panel builders, or integrators looking for a dependable, configurable, and cost-effective thermocouple interface, the DAT2045 is a proven solution in industrial automation environments.
