RTD Input Two-Wire Dual Transmitter DT235

The DT230 series signal conditioners provide two independent I/o channels in one unit.

The DT235 model is a 2 wire dual transmitter. It isolates and converts RTD or linear resistance sensor inputs to a proportional 4-20mA control signal. Power is received from the output loop current or a DC supply when using a three wire connection.

The Acromag DT235 is a RTD Input Two-Wire Dual Transmitter.

Firstly, it accepts RTD (Pt, Ni, Cu) at 0-4500 ohm inputs. Providing sink/source 4-20mA Output using 7-32V DC loop power.

Secondly, the high voltage isolation separates all input and output circuits from each other. The isolation protects from surges, reduces noise and eliminates group loop errors. However, to prevent group loop error between a grounded PC and a grounded input signal, Acromag recommends use of a USB isolator. Setup and calibration is easy. It has a convenient USB connection to your PC and Acromag’s Windows configuration software. Or it can be set up with Android App and your mobile devices.

Finally, with advanced signal processing capabilities, variable input/output range and USB programming make this instrument versatile.  Therefore, it can withstand harsh industrial environments and operate across a wide temperature range with very low drift. Also it features RFI, EMI, ESD, EFT and surge protection as well as low radiated emissions.

Other features of the RTD Input Two-Wire Dual Transmitter DT235 include:

  • Operate as a dual transmitter, a single transmitter, or a signal splitter
