FQA

Q：What voltage input ranges does the DT-3238 support, and what is its resolution?

A：The DT-3238 supports 8 channels of single-ended voltage input with selectable ranges: 0~5VDC, 0~10VDC, ±5VDC, and ±10VDC. Each channel provides high-precision 16-bit analog-to-digital conversion.

Q：Can individual channels be configured or disabled, and is signal filtering adjustable?

A：Yes. Each of the 8 channels can be independently enabled or disabled based on application needs. Additionally, the module allows users to set the filter time per channel to reduce noise and improve signal stability in industrial environments.

Q：What hardware features enhance usability and system reliability for the DT-3238?

A：The module includes an LED indicator for each analog input channel for real-time status monitoring. It also features a high-speed redundant backplane bus and pluggable terminal blocks, enabling easy installation, maintenance, and robust communication within the I/O system.
