Functional specifications

Inputs

Eight independently configurable channels including combinations of 2- and 3-wire RTDs, thermocouples, mV, and 2and 3-wire ohm inputs. 4–20 mA inputs using optional connector(s).

Outputs

Manchester-encoded digital signal that conforms to IEC 61158 and ISA 50.02.

Status

If self-diagnostics detect a sensor burnout or a transmitter failure, the status of the measurement will be updated accordingly.

Ambient temperature limits

–40 to 185 °F (–40 to 85 °C)

Accuracy

(Pt 100 at reference condition: 20 °C) ±0.30 °C (±0.54 °F); for the complete list, see “Accuracy” on page 10.

Isolation

 600 Vdc channel to channel isolation

 10 Vdc channel to channel isolation for all operating

conditions with maximum 150 meters (500 feet) of sensor lead length 18 AWG.

Power supply

Powered over FOUNDATION Fieldbus with standard fieldbus power supplies. The transmitter operates between 9.0 and 32.0 Vdc, 22 mA maximum. (transmitter power terminals are rated to 42.4 Vdc.)

Transient protection

The transient protector (option code T1) helps to prevent damage to the transmitter from transients induced on the loop wiring by lightning, welding, heavy electrical equipment, or switch gears. This option is installed at the factory for the Rosemount 848T and is not intended for field installation.

Update time

Approximately 1.5 seconds to read all eight inputs

(1)

Humidity limits

0–99 percent non-condensing relative humidity

Turn-on time

Performance within specifications is achieved in less than 30 seconds after power is applied to the transmitter.

Alarms

The AI and ISEL function blocks allow the user to configure the alarms to HI-HI, HI, LO, or LO-LO with a variety of priority levels and hysteresis settings.

Electromagnetic compatibility compliance testing

 Meets the criteria under European Union Directive

2004/108/EC.

 Meets the criteria under IEC 61326: 2006.

Stability

 ±0.1% of reading or 0.1 °C (0.18 °F), whichever is greater, for

two years for RTDs.

 ±0.1% of reading or 0.1 °C (0.18 °F), whichever is greater, for

one year for thermocouples.

Self calibration

The transmitter’s analog-to-digital circuitry automatically self-calibrates for each temperature update by comparing the dynamic measurement to extremely stable and accurate internal reference elements.

Vibration effect

Tested to the following with no effect on performance per IEC 60770-1, 1999.

Frequency acceleration

10-60 Hz 0.21 mm peak displacement

60-2000 Hz 3 g

Backup Link Active Scheduler (LAS)

The transmitter is classified as a device link master, which means it can function as a LAS if the current link master device fails or is removed from the segment.

The host or other configuration tool is used to download the schedule for the application to the link master device. In the absence of a primary link master, the transmitter will claim the LAS and provide permanent control for the H1 segment.

1. Reference conditions are -40 to 60 °C (-40 to 140 °F) with 30 meters (100

feet) of sensor lead length 18 AWG wire.

Function blocks

Analog Input (AI)

 Processes the measurement and makes it available on the

fieldbus segment.

 Allows filtering, alarming, and engineering unit changes.

Input Selector (ISEL)

 Used to select between inputs and generate an output using

specific selection strategies such as minimum, maximum, midpoint, or average temperature.

 Since the temperature value always contains the

measurement status, this block allows the selection to be restricted to the first “good” measurement.

Multiple Analog Input Block (MAI)

 The MAI block allows the eight AI blocks to be multiplexed

together so they serve as one function block on the H1 segment, resulting in greater network efficiency.

Differential configuration notes

Differential capability exists between any two sensor types.

For all differential configurations, the input range is X to Y where

X = Sensor A minimum - Sensor B max. Y = Sensor A maximum - Sensor B min.

Accuracy for differential configurations

If sensor types are similar (for example, both RTDs or both thermocouples), the accuracy = 1.5 times worst case accuracy of either sensor type. If sensor types are dissimilar (for example, one RTD and one thermocouple), the accuracy = Sensor 1 Accuracy + Sensor 2 Accuracy.

Analog sensors 4–20mA

Two types of alarm levels are available with 4–20 mA sensors on the Rosemount 848T. These types must be ordered with the S002 option code complete with an analog connector kit. The alarm levels, accuracy for each type are listed in Table 3.
