Safety instrumented systems (SIS) certification

The 3144P Temperature Transmitter is a two wire, 4-20 mA smart device. For safety
instrumented systems usage it is assumed that the 4-20 mA output is used as the primary safety
variable. The transmitter can be equipped with or without the display. The 3144P is classified as
a Type B device according to IEC61508, having a hardware fault tolerance of 0.
The 3144P HART
Safety Instrumented Systems up to SIL 2 and redundant transmitter use in Safety Instrumented
Systems up to SIL 3.
6.2 Rosemount
All 3144P HART transmitters must be identified as safety certified before installing into SIS
systems.
To identify a safety certified Rosemount 3144P, make sure the device satisfies number 1 below
as well as at least one of options 2, 3 or 4.

Verify the transmitter was ordered with Output Option code "A". This signifies that it is
a 4-20mA/HART device.
For example: MODEL 3144PDxA..........
See a Yellow Tag affixed to the outside of the transmitter, or the option code QT in the
transmitter model string.
