Rosemount 3144P temperature transmitter FF fieldbus manual!
power supply
Rosemount temperature transmitter FOUNDAIION fieldbus uses standard fieldbus power supply. The operating voltage of the transmitter is 9 to 32Vdc with a maximum of 11 mA. The rated voltage at the transmitter end is 42.4V dc,
Wiring diagram
Call the police
The analog input function module allows the user to set the alarm to high-high, high, slander or low-low mode according to different priority or lag order.
Transient protection
Transient protectors help prevent the transmitter from being damaged by transients caused by lightning, welding, large electronic equipment or switching equipment. The transient protection electronics are installed in components attached to the standard transmitter junction box. The transient junction box is not sensitive to polarity.
The transient protector has passed the following standard tests:.
ASMEB 16.5 (ANSI) /IEEE 062.41-1991 (IEEE 587), site classification A2, B3,
1kV peak (10 31000 mS wave)
6KV13kA peak value (1.2350 ms wave 8320 ms mixed wave)
6kV 1 0.5kA peak (100 KHz ring color wave)
4kV peak EFT (5 350 nS electrical fast transient pulse)
The loop resistance increased by the protector. Maximum 22 ohms.
Standard clamping voltage: 90V (normal mode), 77V (standard mode)
Display in place
The sensor and function module display all DS.65 measurement results, including: sensor 1, sensor 2, temperature difference and terminal temperature. Up to four options can be displayed. The meter can display five-digit technical units (" F, "C, * R, K,? And microvolts). The display settings can be set in the factory according to the transmitter configuration (standard or custom text). These settings can be reset in the field with a 375 field communication device or Deta V. In addition, the LCD displays the DS_65 parameters of other devices. In addition to instrument configuration, sensor diagnostic data can also be displayed. If the measurement status is good, the measurement value is displayed. If the measurement status is uncertain, it will display in addition to the measured value.
Shows an uncertain state. If the measurement status is poor, the reason for the poor measurement result is displayed.
Start Time
When the decay time is set to zero seconds, the specified performance should be achieved within 20 seconds after the transmitter is powered on.
status
If the automatic diagnosis system detects sensor burnout or transmitter failure, the measurement status will be updated accordingly. The status can also be output by sending a process identifier to a safe value.
FOUNDAIION fieldbus parameters
Plan to introduce devices: 25 (maximum)
Connection device: 30 (maximum)
Virtual Communication Interface (VCR): 20 (maximum)
On-site software upgrade
The 3144P software equipped with FOUNDAION fieldbus is very easy to set up in the field. Make full use of software enhancements by loading application software into device memory.
Alternate Connection Active Scheduler (LAS)
The transmitter can be used as a device to connect to the host. If the current connected host fails or is eliminated from the program segment, it can play the active connection scheduler (LAS) function. Use the host or other configuration tools to download the progress table for applying to connect to the host device. When there is no first connection to the host, the transmitter performs the LAS function and controls the H1 program segment for a long time.
functional module
Resource module
Contains transmitter physical information, including: maximum memory, manufacturing identification, device type, software label and unique identifier.
The factory network alarm system can give full play to the role of the Ir network digital system by diagnosing instrument problems, detailed communication and suggesting solutions.
Sensor module
Contains actual temperature measurement data, including sensor 1, sensor 2 and terminal temperature.
Include the following information: sensor type and configuration, technical units, linearization, range, attenuation and diagnosis.
LCD module (when using LCD display)
Configure the local display.
Mold button input (AI)
. Process the measurement results and use them in the fieldbus program segment.
The filter, technical unit and alarm settings can be changed.
Process identifier module (provides control functions
Perform single loop, cascade or feedforward control in the field.
Real-time function block
The functional modules used by all transmitters are all instantaneous modules, that is, the number of functional modules is only limited by the physical memory in the transmitter. As long as it does not exceed the physical memory in any given time, the combined function module can be used.
