2. Key Selling Points

1. High-Accuracy RTD Temperature Input
   Supports Pt100 and JPt100 (JIS standard) Resistance Temperature Detectors (RTDs) with high measurement accuracy (±0.3°C typical at 0°C), delivering stable and reliable temperature data for precision industrial control applications.

2. 4-Channel Isolated RTD Inputs
   Provides four independent, isolated input channels, enabling simultaneous monitoring of multiple temperature zones—ideal for multi-stage ovens, reactors, HVAC systems, or process heating equipment.

3. Integrated Signal Conditioning & Linearization
   Features built-in excitation current, noise filtering, and automatic linearization, converting raw resistance values into calibrated temperature readings (in °C or °F) without requiring additional programming or lookup tables in the PLC.

4. Compact Design & Direct CPU Integration
   Part of the CP1W expansion module series, it connects directly to CP1E, CP2E, CP1L, or CP1H CPU units via the backplane—no external power supply or wiring required—saving space and simplifying panel layout.

5. Programmable Alarm & Pre-Alarm Functions
   Supports configurable high/low limit alarms and pre-alarms per channel, allowing the PLC to trigger control actions (e.g., cooling, shutdown, warning lights) when temperatures approach or exceed critical thresholds—enhancing system safety and reliability.

6. Excellent Noise Immunity & Electrical Isolation
   Offers channel-to-channel and module-to-PLC isolation, minimizing electrical noise interference and ensuring stable, accurate readings in electrically noisy industrial environments.
