Product Overview

The CJ1W-TC001 adds focused temperature measurement capability to CJ-based control platforms where one critical thermal zone must be monitored accurately. It is suitable for machines using heaters, ovens, or thermal conditioning steps that require dependable feedback to PLC logic. By integrating thermocouple measurement directly in the control rack, the module helps reduce external interface complexity and improves overall maintainability of temperature-aware automation systems.

  • SKU: CJ1W-TC001
  • Series: CJ1W
  • I/O: 1 I/O

Best-Fit Applications

  • Monitoring heater block temperature in sealing machines
  • Reading oven zone temperature in curing or drying processes
  • Supervising hot plate temperature in assembly stations
  • Controlling thermal setpoints in packaging equipment
  • Adding temperature feedback to retrofit CJ control panels
  • Capturing process temperature for quality traceability logic

Buying Checklist

  • Adds focused thermal sensing without major system redesign
  • Ideal when one reliable temperature channel is needed
  • CJ-native integration lowers commissioning overhead
  • Supports better product quality through tighter temperature visibility
  • Good maintenance replacement path for installed CJ systems

FAQ for CJ1W-TC001

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 (high temperature up to 1800°C). Select type in unit setup.
Do I need external cold junction compensation?
No, CJ1W-TC001 has built-in cold junction compensation. Unit measures terminal block temperature and compensates automatically. Ensures accurate temperature reading.
What wire should I use for thermocouple connection?
Use thermocouple extension wire (same type as sensor) or copper wire for short runs. Keep wire away from noise sources. Use terminal block for secure connection.
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.
