JUMO dTRANS T07
Two-channel temperature transmitter with HART/Ex/SIL
for installation into terminal head form B and for installation on DIN rail
Brief description
The JUMO dTRANS T07 device series is a two-channel temperature transmitter with HART
communication. The devices are available in 2 versions: for installation in a B-head or for DIN-
rail mounting. The variants with Ex and SIL approval (IEC 61508) for SIL 2/3 (hardware/software)
enable secure use in demanding process applications.
The configurable transmitters transmit converted signals from RTD temperature probes and ther-
mocouples (TC) as well as from resistor and voltage sensors to the galvanically isolated
4 to 20 mA current output. Internal sensor monitoring functions and device error detection en-
able a high degree of measuring point availability.
The optional plug-on display BD7 can be used to display the current measured value on the B-
head variant.
The JUMO dTRANS T07 device series is tailor-made for all industries like chemicals, oil, gas,
and power plants & energy, as well all others in which safe and reliable temperature measure-
ments are required.

Page 2: Type Overview
Operating mode The temperature transmitters in the dTRANS T07 series are two-wire transmitters with two measurement inputs and one analog output. The devices transmit both converted signals from RTD temperature probes and thermocouples, but also resistance and voltage signals via the HART communication and as a 4 to 20 mA current signal. - Page 3 Temperature-dependent switching between sensors that are used in different measuring ranges. • Average value measurement or differential measurement from two sensors. • Average value measurement with sensor redundancy Not all modes are available for SIL operation SIL safety manual for dTRANS T07 series (SIL designs).
