FQA

Q：What current input ranges does the DT-3434 support, and what is its resolution?

A: The DT-3434 supports 4 channels of current signal input with selectable ranges of 0–20mA or 4–20mA, each featuring high-resolution 16-bit analog-to-digital conversion for precise measurement.

Q：Are the input channels electrically isolated from each other?

A: Yes. Each of the four analog input channels is galvanically isolated from the others, preventing ground loops and enhancing system reliability in industrial environments with varying field potentials.

Q:What user-friendly and system-level features does the DT-3434 offer?

A: The module includes an LED indicator for each of the 4 input channels for real-time status visibility. It also integrates a high-speed redundant backplane bus and pluggable terminal blocks, enabling quick installation, easy maintenance, and stable communication within the remote I/O system.
