Product Overview

The Omron CJ1W-TC002 is a specialized temperature input module for CJ1 series PLCs, designed for precise temperature monitoring in industrial process applications. This module supports 2 channels of thermocouple input, accepting inputs from common thermocouple types including K, J, T, E, and N, providing flexibility for various temperature sensing requirements. The module features high-resolution analog-to-digital conversion, delivering temperature accuracy suitable for demanding process control applications. Each channel can be configured independently, allowing connection of different thermocouple types within the same module for maximum system flexibility. The CJ1W-TC002 performs automatic cold junction compensation, ensuring accurate measurements without external reference junctions. Digital filtering helps smooth noisy temperature signals, improving measurement stability for control system performance. The module connects to thermocouples using dedicated terminal connections, providing secure and organized wiring. Built-in open-circuit detection alerts the PLC when a thermocouple is disconnected or failed, preventing erroneous temperature readings. The CJ1W-TC002 communicates temperature data directly to the CJ1 CPU as digital values, eliminating the need for external signal converters. Applications include temperature monitoring in furnaces, ovens, process tanks, HVAC systems, food processing equipment, and any application requiring temperature data for control or logging.

FAQ for CJ1W-TC002

What thermocouple types are supported?
K (most common, -200 to +1200°C), J (-200 to +900°C), T (-200 to +400°C), E, L, U, N, R, S, B, PLII. Select type in configuration.
Do I need external cold junction compensation?
No, TC002 has built-in cold junction compensation. Unit measures terminal block temperature and compensates automatically.
What wire should I use?
Use thermocouple extension wire (same type as sensor) or copper wire for short runs. Keep wire away from noise sources.
How accurate is this temperature measurement?
±0.3% of full scale ±1 digit. For K-type (0-1000°C range): approximately ±3°C accuracy. For higher accuracy, consider platinum resistance (Pt100) input units.
