Product Overview

The Omron CJ1W-TC001 is a 4-loop thermocouple PID temperature control unit for the CJ-series Special I/O bus, manufactured by Omron Corporation. Hengyixin Automation stocks this controller unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.

The CJ1W-TC001 carries four thermocouple inputs (R, S, K, J, T, B, L) and four NPN open-collector control outputs in one slim 31 x 90 x 65 mm unit, so a single TC001 can run four independent PID loops from one PLC slot. Sampling cycle is 500 ms per channel; indication accuracy is +/- 0.3% of PV or +/- 1 degree C. Control is ON/OFF or 2-DOF PID with auto-tuning.

The TC001 does NOT include heater burnout detection (HBA) — pick the CJ1W-TC003 for that — and does NOT accept Pt100 RTD inputs — pick the CJ1W-TS562 for Pt100. The TC001 takes two consecutive Special I/O unit numbers on the CJ rack. Programming is in CX-Programmer / CX-Process.

Key Features

  • 4-loop thermocouple PID control unit for CJ-series PLCs, 31 x 90 x 65 mm slim
  • 4 TC inputs (R, S, K, J, T, B, L) + 4 NPN open-collector control outputs in one slot
  • ON/OFF or 2-DOF PID control with auto-tuning, 500 ms sampling cycle per channel
  • No heater burnout detection; thermocouple inputs only (not Pt100 RTD)
  • SKU: CJ1W-TC001
  • Series: Omron CJ-series Special I/O temperature control unit

Best-Fit Applications

  • Four-zone heat-seal jaw control on a vertical-form-fill-seal packaging machine, with one K-type TC per zone and four voltage-pulse outputs driving solid-state relays
  • Four-zone reflow oven control on a small SMT line, with a CJ2H-CPU64-EIP scanning all four loops every 2 s and the TC001 handling the PID math locally
  • Plastic-injection barrel zone control on a 4-zone molding machine (barrel, nozzle, mold, hopper), each zone logged to the DM area for shift-end quality reports

Buying Checklist

  • Pick the CJ1W-TC001 for four thermocouple PID loops on one slim CJ Special I/O slot with NPN control outputs.
  • Pick the CJ1W-TC002 instead when the field-side wiring needs PNP sourcing outputs.
  • Pick the CJ1W-TC003 instead when the panel needs heater burnout detection (HBA) on the same 4-loop TC control unit.

FAQ for CJ1W-TC001

What is the Omron CJ1W-TC001?
The Omron CJ1W-TC001 is a 4-loop thermocouple PID temperature control unit for the CJ-series Special I/O bus. It carries four thermocouple inputs (R, S, K, J, T, B, L) and four NPN open-collector control outputs in one slim 31 x 90 x 65 mm unit, so a single TC001 can run four independent PID loops from one PLC slot. Programming is in CX-Programmer / CX-Process.
CJ1W-TC001 vs CJ1W-TC002 — what is the difference?
Output polarity. The CJ1W-TC001 has four NPN (sinking) outputs at 100 mA / 24 VDC. The CJ1W-TC002 has four PNP (sourcing) outputs at the same rating. Both share the same 4 TC inputs, the same 31 x 90 x 65 mm body, and the same PID with auto-tuning. Pick the TC001 for NPN field wiring; pick the TC002 for PNP.
Does the CJ1W-TC001 support heater burnout detection?
No. The CJ1W-TC001 does NOT include heater burnout detection (HBA). Pick the CJ1W-TC003 for PID control with HBA. The TC001 is for straight ON/OFF or 2-DOF PID with auto-tuning only, no current-transformer input.
