Basic Fieldbus Specifications

The 1066pH, the first pH transmitter registered to ITK 6, has the following basic features:
DIAGNOSTICS: Full comprehensive sensor, transmitter, and calibration diagnostics, which are
available to the bus via Field Diagnostics.
COMMON SOFTWARE DOWNLOAD SPECIFICATION: Allows software upgrades to be down-
loaded to the transmitter, while it is in service.
LINK ACTIVE SCHEDULER: Allows the 1066pH to function as a Linkmaster.
4 AI FUNCTION BLOCKS: For PV (pH, ORP, Redox), temperature, reference electrode impedance,
and glass electrode impedance.
AO FUNCTION BLOCK: Allows the transmitter to use a temperature measurement from the bus for
temperature compensation.
ADDITIONAL FUNCTION BLOCKS: Are provided for use by the 1066-P-FF or other transmitters on
the segment, and include:
MATH FUNCTION BLOCKS: Arithmetic and Integrator
ANALOG CONTROL FUNCTION BLOCKS: PID Control, Input Selector, Signal Characterizer, Control
Selector, and Output Splitter.
Input: One isolated pH/ORP sensor input.
Power & Load Requirements: Fieldbus power voltage at 9 to 32 VDC. Current required is 18 mA.
