Specifications and Reference Data
Control selector block
 The control selector Function Block selects one of two
or three inputs to be the output. The inputs are
normally connected to the outputs of PID or other
function blocks. One of the inputs would be
considered Normal and the other two overrides.
Output splitter block
 The output splitter function block provides the
capability to drive two control outputs from a single
input. It takes the output of one PID or other control
block to control two valves or other actuators.
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.
PROFIBUS PA (output code W)
Profile version
3.02
Power supply
External power supply required; transmitters operate on
9.0 to 32.0 Vdc transmitter terminal voltage for non-I.S.
applications, 9.0 to 30 Vdc for entity model intrinsically
safe applications and 9.0 to 17.5 Vdc for FISCO intrinsically
safe applications.
Current draw
17.5 mA for all configurations (including LCD display
option)
Output update rate
Four times per second
Standard function blocks
Analog Input (AI Block)
 The AI function block processes the measurements
and makes them available to the host device. The
output value from the AI block is in engineering units
and contains a status indicating the quality of the
measurement.
Physical block
 The physical block defines the physical resources of
the device including type of memory, hardware,
electronics, and diagnostic information.
Transducer block
 Contains actual sensor measurement data including
the sensor diagnostics and the ability to trim the
pressure sensor or recall factory defaults.
Indication
 Optional 2-line LCD display
LOI
 Optional external configuration buttons.
Wireless (output code X)
Output
IEC 62591 (WirelessHART), 2.4 GHz DSSS
Wireless radio (internal antenna, WP5 option)
 Frequency: 2.400 - 2.485 GHz
 Channels: 15
 Modulation: IEEE 802.15.4 compliant DSSS
 Transmission: Maximum of 10 dBm EIRP
Local display
The optional 3-line, 7-digit LCD display can display
user-selectable information such as primary variable in
engineering units, scaled variable, percent of range,
sensor module temperature, and electronics
temperature. The display updates based on the wireless
update rate.
Digital zero trim
Digital Zero trim (option DZ) is an offset adjustment to
compensate for mounting position effects, up to 5% of
URL.
Update rate
User selectable 1 sec. to 60 min.
Wireless sensor module for In-Line transmitters
The 2051 Wireless Transmitter requires the engineered
polymer housing to be selected. The standard sensor
module will come with aluminum material. If stainless
steel is required, the option WSM must be selected.
Power module
Field replaceable, keyed connection eliminates the risk of
incorrect installation, Intrinsically Safe Lithium-thionyl
chloride Power Module with PBT/PC enclosure. Ten-year
life at one minute update rate.
(1)
1. Reference conditions are 70 °F (21 °C), and routing data for three
additional network devices.
Note: Continuous exposure to ambient temperature limits of -40
°F to 185 °F (-40 °C to 85 °C) may reduce specified life by less than
20 percent.
