The DAT2014 is a 2-channel Modbus RTU converter designed for RTD and resistance sensors. It functions as a Modbus slave device, transmitting precise temperature and resistance data to PLCs, HMIs, or SCADA systems over the RS-485 network.

What types of inputs does it support?

The device supports 2- or 3-wire RTD sensors (such as Pt100, Pt1000, Ni100) and generic resistance inputs, offering flexibility for temperature and process monitoring applications.

How is the DAT2014 configured?

The module can be configured remotely via the RS-485 interface using free configuration software. Communication parameters such as address, baud rate, and parity can be set to match the network requirements.

Does the device provide isolation?

Yes. The DAT2014 provides 1000 Vac galvanic isolation between the input channels, power supply, and communication lines, ensuring reliable measurements and protection from ground-loop interference.

What is the power supply requirement?

The converter operates from a 10–30 VDC power supply, compatible with standard industrial control panels and systems.

How many channels does it have?

The DAT2014 features 2 isolated input channels, allowing two independent RTD or resistance sensors to be connected simultaneously.

General Description

The DAT2014 is a 2-channel RTD and resistance input to Modbus RTU converter designed for high-accuracy temperature and resistance measurement across an RS-485 network. Each input channel is galvanically isolated, supporting the connection of 2- or 3-wire RTD sensors and resistance inputs with excellent stability over time and temperature.

Communication is managed through the Modbus RTU or Modbus ASCII protocol, allowing seamless integration with PLCs, HMIs, and SCADA systems. The module offers 1000 Vac isolation between input, power supply, and communication lines—eliminating ground-loop effects and ensuring reliable operation even in harsh industrial environments.

To ensure system safety, the DAT2014 includes a Watch-Dog timer alarm, while front-panel LEDs provide visual indication of power status, communication activity, and initialization conditions. The unit can be remotely configured for easy installation and maintenance. Housed in a 1-module DIN rail enclosure made of self-extinguishing plastic, the DAT2014 combines compact design with durability, conforming to EN-50022 standards.
