ENCLOSURE: IP66
The country of origin.
Can be operated in the field without opening the cover using optical switches.
Display: 6-digit LCD
Switch: Three optical switches
Output Signal: 4 to 20 mA DC, one point (maximum load resistance 550
⍀)
Digital Communication (HART): 250 to 550
⍀, depending on quantity of field
devices connected to the loop (multi-drop mode).
Note: HART is a registered trademark of the HART Communication Foundation.
Contact Output Signal: Two points (one is fail-safe, normally open)
Contact Input Signal: Two points
Sample Gas Temperature: 0 to 700
ЊC
It is necessary to mount the cell using Inconel cell-bolts when the tem-
perature measures more than 600
ЊC.
High-temperature service—greater than 700
ЊC—is not available.
