Product Overview

The Allen‑Bradley 2080‑RTD2 is a 2‑channel, non‑isolated resistance thermometer detector (RTD) input module designed as a plug‑in expansion for the Micro800™ programmable logic controller family . As a specialty analog module within the Bulletin 2080 Micro800 system, the 2080‑RTD2 enables precise temperature measurement by directly interfacing with a wide variety of RTD sensors, making it an essential component for applications requiring accurate and reliable temperature monitoring without the need for external signal conditioning or transmitters. This module is specifically engineered for use with Micro810, Micro830, and Micro850 controllers, installing directly into any available plug‑in slot on the base unit to extend functionality without increasing the controller’s physical footprint .

The Allen‑Bradley 2080‑RTD2 supports an extensive range of RTD types, including Platinum (100, 200, 500, and 1000 Ω with both 385 and 392 alpha coefficients), Copper (10 Ω 427), Nickel (120 Ω 672), and Nickel‑Iron (604 Ω 518) sensors, providing exceptional flexibility for diverse temperature measurement applications . The module features 14‑bit resolution and delivers accuracy of ±1.0°C at 25°C, with configurable update rates ranging from 4.17 Hz to 470 Hz to balance speed and noise rejection based on application requirements . Through simple software configuration in FactoryTalk Design Workbench or Connected Components Workbench, each channel can be independently configured for RTD type and data update rate, and the 2080‑RTD2 provides comprehensive diagnostic status including open circuit detection, over‑range, under‑range, and calibration error flags to ensure measurement integrity . With its compact dimensions, removable terminal blocks, and integration with the Micro800 ecosystem, the Allen‑Bradley 2080‑RTD2 offers a cost‑effective and space‑efficient solution for temperature monitoring in small to mid‑sized industrial automation applications.
