RTU or ASCII, Response time : 25 to 50 ms
FOUNDATION
fieldbus
AI block × 4, IT block × 2, with Link Master function
PROFIBUS PA AI block × 4, TOT block × 2
Damping (default)
Flow rate 0.8sec, density 4sec, temperature 2.5sec.
Low flow cutoff (default)
Under 0.6% of max. service flow rate
Pulse output ( ※ 5)
Open drain output (equivalent to open collector output ) [Min. 10V to Max. 30V, 50mADC, ON
resiatance 0.6Ω or less] or
Voltage pulse (Low level: 1.5V max., High level: 13V min. Output impedance: 2.2k Ω )
Setting range: 0.1 to 10000Hz (Max. output 11000Hz)
Analog output ( ※ 5)
4 to 20mADC (max. load 600Ω)
Select two outputs from instant flowrate (mass or volume) temperature, and density.
Status output ( ※ 5)
Open drain output (equivalent to open collector output ) [Max. 30V, 50mADC, ON resiatance
0.6Ω or less]
Select one output from error ( ※ 4), flow direction, or high/low alarm (default is error)
Status input ( ※ 5)
Contact-closure input (Form "a" contact) Short: 200 Ω max., Open: 100k Ω min.
Select one output from remote zero, total reset, 0% signal lock, or function off (default is
function off).
※1: Below -20℃, the display loses its visibility due to weakened contrast. Both the display and infrared sensor
may exhibit slow responses below -20℃.
※2: If signal transmission length exceeds the maximum transmission length, consult OVAL.
※3: Of the two analog output systems,only analog output 1 is available for HART communication.
※4: Of error outputs, "zero is in progress" status output can also be set up.
※5: When FOUNDATION fieldbus, PROFIBUS PA is selected as the communication interface, all input and
output signals will be turned off.
※: Denoising parts are embedded in the lines between power source, output, communication, and the chassis.
Lower the applied voltage to the following levels in order to conduct insulation test or withstand voltage test
on these lines.
AC: 200V, DC: 250V
