Thermocouple Input - Signal Converters, Transmitters

• Universal TC type J, K, T, R, S, E, B, N or ±100mV input
• 4-20mA ouput (sink/source)
• 12-32 V DC loop/local power

The TT233 model is a space-saving two-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current or a DC supply when using a three-wire connection. Click here to watch a short AcroMaggie video highlighting the TT230 Series.        

• Universal thermocouple / millivolt input
• Universal current / voltage output
• 12-32V DC local / bus power

The TT333 model is a space-saving four-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional control signal. DC current and voltage output are both supported on a single model. Click here to watch a short video highlighting the TT330 Series.    

• Universal thermocouple (8 types) or ±100mV input
• 4-20mA output
• Loop-powered, 7-32V DC

The ST132 is a low-cost two-wire transmitter that converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. The transmitter performs signal linearization, cold-junction compensation, and lead-break detection functions.  

• TC type J, K, T, R, S, E, B, and N or ±100mV input
• 1500V isolation
• 4 to 20mA DC output
• USB-configured
