Model Number

848T

•	Accepts eight independently configurable RTD, thermocouple, ohm, and millivolt inputs
•	Industry first Measurement Validation Diagnostic can detect data abnormalities before a shutdown condition occurs and can identify on-scale failures
•	Powers PlantWeb® by providing multi-sensor measurement capabilities and diagnostics in one transmitter
•	Reduces the need for signal wiring and can cut capital expenditures by up to 70% when compared to traditional temperature architectures.
•	Installs next to process for shorter wire runs reducing the effects of electromagnetic interference from nearby electrical equipment
•	Easily integrates existing analog instrumentation into FOUNDATION fieldbus environment with the added digital features including:

	-	2 Multiple Analog Input (MAI) function blocks to efficiently communicate all eight measurements at once
	-	4 Input Selector (ISEL) function blocks for selecting Average, Minimum, Maximum, Midpoint, or First Good Status Temperatures
	-	Backup Link Active Scheduler (LAS) ensures measurement availability
	-	8 Analog Input (AI) function blocks to communicate individual measurements with alarming

Communicates up to 128 temperature measurements on two wires using innovating High Density technology
