2. Key Selling Points

1. High-Accuracy RTD Temperature Input Module
   Specifically designed for Resistance Temperature Detector (RTD) inputs, supporting Pt100 and Pt1000 sensors with high precision—ideal for applications requiring stable and accurate temperature measurement.

2. 4-Channel Independent Inputs
   Provides 4 isolated RTD inputs, allowing simultaneous monitoring of up to 4 temperature points—perfect for multi-zone temperature control in ovens, reactors, or climate chambers.

3. Built-in Excitation Current & Linearization
   Features integrated excitation current circuits and automatic linearization, converting raw resistance values into accurate temperature readings (in °C or °F) without additional programming or lookup tables.

4. Compact Size & Seamless Integration with CP1 Series PLCs
   Part of the CP1W expansion module family, it connects directly to CP1E, CP1L, CP2E, or CP1H CPU units via the backplane—no external power or wiring required—saving space and simplifying system design.

5. Flexible Alarm & Pre-Alarm Functionality
   Supports high/low limit alarms and pre-alarms per channel, enabling real-time alerts and automated control responses (e.g., cooling activation or process halt) when temperatures exceed safe ranges.

6. Excellent Noise Immunity & Signal Stability
   Offers channel-to-channel isolation and built-in digital filtering, ensuring reliable performance and stable readings even in electrically noisy industrial environments.
