Minco TT269 Installation And Operating Instructions

3-wire temperature transmitter

Model TT269 is a 3-wire temperature transmitter for RTD (resistance temperature detector)

thermometers. The Temptran

current changes according to the range marked on the Temptran: 0 mA at the lowest

temperature of the range, rising to 1 mA at the top of the range.

Locate the Temptran near the RTD, in an area where the ambient temperature stays between -

40 and 85 °C (-40 and 185 °F). Mount with #8 machine screws using the two mounting holes

provided in the Temptran case.

Connect the Temptran as shown below, observing the +/- polarity of the power supply

connections. Maximum DC supply voltage = 35 VDC. The maximum load resistance for the 0

to 1 mA output is 1000 Ω . The RTD connections for the Temptran in the wiring diagram below

must be connected as shown or the transmitter will not function properly.

3-wire Temperature Transmitter Installation and Operating Instructions Description Model TT269 is a 3-wire temperature transmitter for RTD (resistance temperature detector) thermometers.

The current changes according to the range marked on the Temptran: 0 mA at the lowest temperature of the range, rising to 1 mA at the top of the range.
Page 2 Calibration NOTE: Because the transmitter cannot output a negative current, the calibration of the zero cannot be performed at 0 °C (0 mA). The zero calibration should be performed at 6 °C (.05 mA) to ensure proper calibration of the transmitter. If the transmitter is calibrated at 0 °C, the output of the transmitter may not be linear.
