4-20mA Signal Isolator TT236

The Acromag Model TT236 is a 4-20mA Signal Isolator is a two-wire transmitter. It isolates and converts a DC current or low voltage input into a proportional 4-20mA control signal.  Additionally, a single unit supports both voltage and current input for extra flexibility. Furthermore, power comes from the output loop current or a DC supply when using a three-wire connection.

Firstly, high-voltage isolation separates the input from the output circuit. Plus, the isolation protects from surges, reduces noise, and eliminates ground loop errors. Set-up and calibration are also fast and easy.  For example,  a USB connection on your PC and Acromag’s Windows configuration software is all you need for set up.

Finally, The TT236 is a versatile temperature measurement device. This is a result of its advanced signal processing capabilities, variable range input, and convenient USB programming.  This signal isolator is also withstands harsh industrial environments and operates reliably across a wide temperature range with very low drift. It also features RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.

IMPORTANT: To prevent damage or errors from grounded PCs and surges Acromag strongly recommends using their USB-ISOLATOR when configuring a TT230 Series transmitter.
