| • | 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 |
