Analog Current Output Module 4AO

DT-4234 Analog Current Output Module 4AO Module Features The DT-4234 4-channel analog current output module by Sichuan Odot is engineered for industrial applications demanding high-precision, noise-immune 4–20mA or 0–20mA signal transmission. It delivers 4 independent current output channels, each configurable for 0–20mA or 4–20mA ranges—ideal for driving control valves, remote indicators, transmitter simulators, and other field devices. A key differentiator is its capacitive isolation between the internal backplane bus and field outputs, which eliminates ground loops and ensures signal integrity even in electrically noisy environments (e.g., near VFDs or high-voltage machinery). Outputs use a single-ended, common-ground architecture, ensuring broad compatibility with standard industrial receivers and simplifying integration. Built on a high-speed redundant backplane bus, the module supports rapid data refresh for responsive closed-loop control, while pluggable terminal blocks enable…
