Rosemount 2051

Reference Manual

00809-0200-4101, Rev AA July 2008

LCD Block

• Configures the local display.

2 Analog Input Blocks

•Processes the measurements for input into other function blocks. The output value is in engineering units or custom and contains a status indicating measurement quality.

PID Block

•Contains all logic to perform PID control in the field including cascade and feedforward.

Backup Link Active Scheduler (LAS)

The transmitter can function as a Link Active Scheduler if the current link master device fails or is removed from the segment.

Overpressure Limits

1-5 Vdc HART Low Power (Output Code M)

Output

Three wire 1–5 Vdc output, user-selectable for linear or square root output. Digital process variable superimposed on voltage signal, available to any host conforming to the HART protocol.

Power Supply

External power supply required. Standard transmitter operates on 9 to 28 Vdc with no load.

Power Consumption

3.0 mA, 27–84 mW

Output Load

100 kΩ or greater

Turn-On Time

Performance within specifications less than 2.0 sections after power is applied to the transmitter.

Transmitters withstand the following limits without damage:

4500 psig (310,3 bar) for option code P9

• Range 1: 2000 psig (137,9 bar)

2051T

•Range 1: 750 psi (51,7 bar)

•Range 2: 1500 psi (103,4 bar)

•Range 3: 1600 psi (110,3 bar)

•Range 4: 6000 psi (413,7 bar)

•Range 5: 15000 psi (1034,2 bar)
