Thermocouple mV Input 4-Wire Transmitter TT333

The TT333 model is a four-wire transmitter that isolates and converts thermocouple or millivolt sensor inputs to proportional control signal. Power is received from the DC Local / bus power.

The Acromag TT333 is a Thermocouple mV Input 4-Wire Transmitter.

Firstly, this model is a four wire transmitter and converts thermocouple or millivolt inputs. It converts these inputs into a proportional control signal. DC Current and Voltage outputs supported on single model. Optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.

Secondly, the high voltage isolation separates the input from the output circuit. As well as Isolation protects against surges, reduces noise and eliminates ground loop errors.

Thirdly, Setup and calibration are quickly achieved with a convenient USB connection to your PC and Acromag’s Windows configuration software. The Android app enables setup with mobile devices. This instrument is very versatile with its advanced signal processing capabilities and variable input/output and USB programming. It can withstand harsh environments and operates across a wide temperature range. It features RFI, EMI, ESD, EFT and surge protection plus low radiated emissions.

Features of the Thermocouple / millivolt Input 4-Wire Transmitter TT333 includes:

  • Easy setup and digital calibration via USB with Windows configuration software
  • Universal thermocouple or millivolt input (TC Type J, K, T, R, S, E, B, N or ±100mV)
