RTD Input Two-Wire Transmitter TT231

The Acromag TT231 is a RTD Input Two-Wire Transmitter.

Firstly, it accepts 100 ohm PT RTD or 0-900 ohm inputs. Producing a 4-20mA sink/source output where power is received from the output loop current or a DC supply when using a three wire connection.

Secondly, to prevent group loop error between a grounded PC and a grounded input signal, Acromag recommends use of a USB isolator. Setup and calibration are easy. It has a convenient USB connection to your PC and Acromag’s Windows configuration software.

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

Other features of the RTD Input Two-Wire Transmitter TT231 include:

• Easy setup and digital calibration via USB with Windows configuration software
• Flexible RTD or linear resistance input ranges (any 100 ohm Pt RTD with 375-393 alpha)
• Space-saving 12.5mm unit with pluggable terminals for convenient wiring
• As well as high accuracy, linearity, stability, and reliability
