Transmitter, Isolated RTD Input, DC Local/Bus Power
• Selectable RTD or linear resistance input type or 0-500 ohm input
• Universal output (source)
• 12-32V DC local/bus power
• USB configuration
The TT335 model is a space-saving four-wire transmitter that isolates and converts an RTD sensor input to a proportional control signal. DC current and voltage output are both supported on a single model. An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.more >
High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors.
Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.
Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature measurement device. These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
