1. Main Specifications 

2. Key Selling Points

1. High-Precision Thermocouple Input
   Supports 8 thermocouple types (K, J, T, E, L, U, R, S) with high accuracy (±1°C typical), enabling reliable temperature monitoring in industrial heating, processing, and control applications.

2. 4-Channel Isolated Inputs
   Provides four independent, isolated thermocouple channels, allowing simultaneous monitoring of multiple temperature zones—ideal for multi-zone furnaces, ovens, reactors, or injection molding machines.

3. Built-in Cold Junction Compensation (CJC)
   Features automatic cold junction compensation at each terminal block, ensuring accurate temperature readings by compensating for ambient temperature variations—no external sensor required.

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 needed—saving panel space and simplifying system integration.

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) when temperatures approach or exceed safe limits—enhancing process safety and reliability.

6. High Noise Immunity & Signal Filtering
   Offers channel-to-channel and module-to-PLC isolation, along with built-in digital filtering, to minimize electrical noise interference and ensure stable, accurate readings in electrically noisy industrial environments.
