Local operator interface

The LOI utilizes a 2 button menu with 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 3051 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

Low power output

1-5 Vdc HART Low Power (output code M)

Output

Three-wire 1-5 Vdc (option code C2) user-selectable output.

Also user selectable for linear or square root output

configuration. Digital process variable superimposed on voltage

signal, available to any host conforming to the HART protocol.

Low-power transmitter operates on 6-12 Vdc with no load.

Power consumption

3.0 mA, 18-36 mW

Minimum load impedance

100 k (V

(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 or

185 °F (-40 °C or 85 °C) may reduce specified life by less than 20

percent.
