2.2 General description
TT 11 C TT 11 C TT 11 C TT 11 C
The TT 11 C is an analogue multi-range 3-wire in-head transmitter for temperature
measurements. It works together with measuring resistors of the types Pt100 and Pt1000. The
device has an output with the range 0...10 VDC; the manufacturer has designed the transmitter
especially for building services applications as HVAC systems often require a signal in the range
of 0...10 V.
The in-head transmitter is intended for installation in a "B connection head" or larger according
to DIN 43729. As an alternative you can also mount the in-head version on a rail according to
DIN EN 50022 with the help of the rail mounting kit (further information on page 14).
TT 11 R TT 11 R TT 11 R TT 11 R
The TT 11 R is an analogue 3-wire rail-mount transmitter for temperature measurements with
the same features as the in-head version.
The rail-mount transmitter is intended for installation on a rail according to DIN 50022.
INFORMATION!
In the standard delivery condition the transmitters are not preset. Therefore you have to make a
complete solder pad configuration before using the transmitter for the first time (refer to
chapter "Operation"). As an option the manufacturer offers preset transmitters according to the
customer's order.
