Loop Power RTD 2-Wire Transmitter TT235

The Acromag TT235 is a loop power RTD Input 2-Wire Transmitter.

Firstly, it accepts selectable RTD or linear resistance input type or 0-500 ohm inputs. Producing 4 to 20 mA proportional output using 12-32V DC from local/loop power. It is also USB configured.

Secondly, setup and calibration are fast and easy. Simply by using the USB Connection to your PC and Acromag’s Windows configuration software. This temperature instrument is versatile with its advanced signal processing capabilities, variable range input and convenient USB programming. Therefore, designed to withstand harsh industrial environments and operate across a wide temperature range with low drift. It features RFI, EMI, ESD, EFT and surge protection plus low radiated emissions. In order to prevent damage or errors from grounded PCs and surges, Acromag strong recommends use of a USB Isolator when configuring the TT230 Series transmitter.
