TT269
3-wire Temperature Transmitter
Installation and Operating Instructions
Description
Model TT269 is a 3-wire temperature transmitter for RTD (resistance temperature detector)
thermometers. The Temptran
TM
converts the RTD's signal into a 0 to 1 mA current. 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.
Installation
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.
