Omron CP1W-TS004 CP Series Temperature Sensor Unit

Description

Integrating thermal measurement directly into micro-PLC configurations, the CP1W-TS004 functions as a high-precision thermocouple input expansion module. Engineered for seamless coupling with Omron CP-series controllers, including the CP1E, CP1L, and CP1H, this module facilitates the direct connection of up to four temperature sensors without requiring external signal conditioning or transmitter hardware.

The unit converts analog thermal data from K-type or J-type thermocouples into digital values, transmitting them directly to the PLC CPU memory area. This direct-bus connection minimizes signal degradation over long distances, simplifies overall system wiring, and reduces control cabinet space requirements by eliminating independent DIN-rail temperature transmitters.

Features

• Supports up to 4 independent thermocouple inputs.
• Compatible with Type K and Type J thermocouple sensors.
• Direct integration with CP-series micro-PLC backplanes.
• Photocoupler isolation between the input channels and internal PLC circuitry.
• Simple DIN-rail or screw mounting options for rapid physical installation.

Applications

• Industrial heating and cooling control systems.
• Packaging machinery heat-sealing bars.
• Plastic extrusion and injection molding thermal zones.
• Food processing pasteurization and cooking loops.
• HVAC environmental chamber monitoring.

Installation Guidelines

• Mounting: Mount securely onto standard 35mm DIN rail or utilize integrated screw mounting holes for direct backpanel attachment inside an industrial enclosure.
• Wiring: Always use specified thermocouple compensation/extension cables that match the sensor type (K or J). Do not route thermocouple wires in the same duct or conduit as high-voltage power lines to prevent electromagnetic interference.
• Grounding: Connect the functional ground terminal on the main PLC CPU to a dedicated, low-impedance ground point (100 Ohms or less).
• Ventilation: Ensure a minimum vertical clearance of 50mm above and below the expansion unit to maintain proper thermal convection.
