SAFETY
INSTRUMENTED
SYSTEMS (SIS)
CERTIFICATION
The safety-critical output of the 3051S with Advanced HART Diagnostic is
provided through a two-wire, 4 - 20 mA signal representing pressure. The
3051S safety certified pressure transmitter is certified to: Low Demand; Type
B.
SIL 2 for random integrity @ HFT=0
SIL 3 for random integrity @ HFT=1
SIL 3 for systematic integrity
3051S Safety Certified
Identification
All 3051S transmitters must be identified as safety certified before installing
into SIS systems.
NOTE
There are three versions of safety certified 3051S pressure transmitters. For
transmitters with a yellow SIS circuit board installed (Output code B), please
refer to Manual Supplement 00809-0700-4801. For transmitters without the
Advanced HART Diagnostics circuit board installed, please refer to Section 6:
Safety Instrumented Systems.
To identify a safety certified 3051S with Advanced HART Diagnostics:
1. Connect a HART host to the transmitter.
2. Check transmitter Revision numbers to verify that Electronics SW rev is
10 or higher and Sensor SW rev is 5 or higher.
Fast Key Sequence - 1, 3, 5, 3
3. Verify that option code DA2 is included in the transmitter model code.
3051S SIS Installation No special installation is required in addition to the standard installation
practices outlined in this document. Always ensure a proper seal by installing
the electronics housing cover(s).
Environmental limits are available in the 3051S Product Data Sheet
(document number 00813-0100-4801). This document can be found at

The loop should be designed so the terminal voltage does not drop below
12.0 Vdc when the transmitter output is 23.0 mA.
Security switch should be in the “ON” position during normal operation. See
Figure 7-30 on page 7-38.
