Description

The Omron CP1W-TS102 is a dedicated temperature sensor input expansion unit designed for the CP-series programmable logic controller platform, including compatibility with CP1E, CP1L, CP1H, and CP2E micro PLC systems. The primary purpose of this hardware module is to accurately acquire multi-channel analog temperature process values from the field and convert them into digital data registers over the PLC internal extension bus. The hardware features 4 dedicated analog temperature input channels specifically configured to interface with Pt100 Resistance Temperature Detectors (RTD). It utilizes high-resolution 12-bit analog-to-digital conversion arrays to output stable, linear temperature profiles directly to the central processing unit without requiring separate signal conditioners. This unit functions as an essential automation component for industrial thermal processing lines, packaging machinery, and commercial climate monitoring skids.

Features

• High-density temperature monitoring unit featuring 4 independent Pt100 RTD sensor inputs.
• Built-in 12-bit analog-to-digital resolution framework guaranteeing reliable thermal tracing.
• Native micro bus coupling for direct seamless data integration with CP-series controller blocks.
• Removable front terminal block mechanism for simplified, rapid maintenance routing.
• Compact modular engineering enclosure optimizing spatial usage inside tightly packed control panels.

Applications

• Multi-zone industrial heating ovens, continuous tunnel kilns, and drying machinery.
• Packaging machinery sealing bars, forming jaw thermal loops, and hot-melt glue systems.
• Plastic injection molding temperature zones and extrusion barrel thermal management.
• Food processing pasteurization loops, commercial baking lines, and cold storage monitoring.
• Environmental monitoring control nodes, HVAC climate automation, and cooling tower skids.

Installation Guidelines

• Bus Interconnection: Ensure the main PLC CPU base block power is completely switched off before engaging the side extension cable. Push the flexible ribbon cable clip into the adjacent unit socket until it is firmly locked.
• DIN Rail Assembly: Mount the expansion module horizontally onto a standard 35mm DIN rail profile inside the control sub-panel enclosure. Use standard end plate clamps to lock the system footprint rigidly against operational vibration.
• Sensor Wire Shielding: Always employ high-quality three-wire shielded cables for all connected Pt100 RTD sensors. Connect the cable shield wraps cleanly to a common panel earth point to suppress external high-frequency EMI noise.
• Signal Channel Routing: Separate RTD sensor signal cables completely from heavy AC power distribution cables, motor drive lines, or inductive contactor wiring to prevent electrostatic coupling from corrupting the 12-bit conversion.
• Compensated Terminal Tightening: Secure the terminal block interface screws systematically, ensuring uniform torque to minimize terminal-to-wire contact resistance changes which could skew RTD resistance calculations.

FAQ

What specific type of temperature sensors does this expansion module support?

The module is designed exclusively to interface with Pt100 resistance temperature detectors.

How many independent sensor channels are available on the module?

The unit provides a total of 4 discrete analog temperature input channels.

What is the internal analog-to-digital conversion resolution of the inputs?

The input channels process the thermal variations through an integrated 12-bit digital resolution register array.

Can this unit be used to output a 4-20 mA control signal to a proportional valve?

No, this specific model features 0 analog outputs and does not contain linear current or voltage output capabilities.

With which Omron PLC platforms is this expansion card fully compatible?

It is compatible with standard CP-series micro controllers including the CP1E, CP1L, CP1H, and CP2E CPU series.

Does the module require separate programming software for configuration?

No, the configuration registers and temperature tracking values are accessed directly using standard memory addresses inside CX-Programmer or Sysmac Studio.

What are the baseline physical outer dimensions of the housing?

The module measures 90 mm in height, 86 mm in width, and 50 mm in depth.

How much does this module weigh for control panel mechanical weight calculations?

Why is it critical to use a 3-wire wiring configuration for the Pt100 probes?

The 3-wire setup allows the internal conversion circuitry to automatically calculate and cancel out the natural electrical resistance introduced by long field cable lengths.

Can I plug or unplug the expansion ribbon cable while the PLC is actively powered up?

No, always isolate and turn off the primary system power supply before adding, removing, or servicing expansion bus connections to avoid destroying the logic circuitry.
