FQA

Q：What current output ranges and resolution does the DT-4234 module support?

A：The DT-4234 offers 4 analog current output channels, each configurable as either 0–20 mA or 4–20 mA, with 16-bit resolution—meeting industrial standard signal requirements and high-precision control needs.

Q：What electrical isolation and safety features does the DT-4234 incorporate?

A：The module uses capacitive isolation to provide reliable electrical separation between the internal bus and field outputs, effectively preventing ground loops and high-voltage transients from compromising system safety and stability.

Q：Is the DT-4234 easy to install and maintain?

A：Yes. Built on a high-speed redundant backplane bus, it features pluggable spring-clamp terminals (supporting wire sizes from 0.2 to 1.5 mm² / AWG 24–16), enabling rapid wiring and tool-free replacement for efficient installation and maintenance.
