Thermocouple mV Input 2-Wire Dual Transmitter DT233

The DT233 model is a dual two-wire transmitter that isolates and converts thermocouple or millivolt sensor inputs to proportional 4-20mA control signals. Power is received from the output loop current.

The Acromag DT233 is a Thermocouple mV Input 2-Wire Dual Transmitter.

Firstly, this model has dual channels and accepts universal thermocouple and millivolt inputs. It converts these inputs into 4-20mA outputs (sink/source) using 7-32V DC loop/local power supply. The DT230 series signal conditioners provide two independent I/O channels.

Secondly, high voltage isolation separates all input and output circuits from each other. Isolation protections from surges, reduces noise and eliminates ground loop errors. However, Acromag highly recommends the use of USB Isolator when calibrating this product.

Thirdly, Setup and calibration are quickly achieved with a convenient USB connection to your PC and Acromag’s Windows configuration software. The Android app enables setup with mobile devices. This instrument is very versatile with its advanced signal processing capabilities and variable input/output and USB programming. It can withstand harsh environments and operates across a wide temperature range. It features RFI, EMI, ESD, EFT and surge protection plus low radiated emissions.
