The OMRON CP1W-TS002, also cataloged as the CP1W Temperature Sensor Unit, provides four thermocouple input channels for temperature measurement in OMRON CP-series PLC systems. It accepts either J-type or K-type thermocouples, with the selected thermocouple type applied consistently across all inputs. Temperature conversion data is transferred as 16-bit binary values.

Hardware Specifications

OMRON PLC Temperature Input Architecture

The CP1W-TS002 is an expansion temperature sensor unit for OMRON CP-series PLC architectures. Its four thermocouple channels occupy four input words, allowing each temperature measurement to be represented in the CPU input area as converted binary data. The module supports J-type or K-type thermocouples, but all connected channels must use the same selected thermocouple type.

The temperature conversion process uses a 250 ms conversion time for two or four active input points. Photocoupler isolation is provided between the temperature input signals. This electrical separation should be considered when wiring thermocouple circuits and establishing the control-panel grounding arrangement.

Field Installation Guidelines

• Install the CP1W-TS002 as an expansion unit within the supported OMRON CP-series PLC configuration.
• Configure all four temperature inputs for the same thermocouple type, either J or K.
• Do not mix J-type and K-type thermocouples on the same CP1W-TS002 configuration.
• Keep thermocouple wiring separated from high-voltage power conductors, motor cables, and high-current switching circuits.
• Use thermocouple extension or compensating cable appropriate to the selected thermocouple type.
• Maintain correct thermocouple polarity throughout the sensor circuit.
• Avoid unnecessary junctions between thermocouple conductors and ordinary copper wiring.
• Route temperature input wiring with appropriate shielding where the installation is exposed to electrical noise.
• Connect panel grounding according to the PLC system installation requirements rather than creating independent uncontrolled ground paths.
• Verify the configured thermocouple type and channel allocation before applying the converted temperature values in the PLC program.
• Confirm that the available CPU input-word allocation matches the four words required by the module.

Frequently Asked Questions

• Can CP1W-TS002 accept both J-type and K-type thermocouples simultaneously?

  No. The module is switchable between J and K thermocouple operation, but the same thermocouple type must be used for all inputs.

• How many thermocouple inputs does CP1W-TS002 provide?

  CP1W-TS002 provides 4 thermocouple input channels. The module allocates 4 input words for the converted temperature data.

• What is the temperature conversion time?

  The specified conversion time is 250 ms for 2 or 4 input points. The converted temperature values are transferred as 16-bit binary data.

• What data format is produced by the module?

  Temperature data is converted into 16-bit binary data represented as 4-digit hexadecimal values for processing within the PLC input area.

• Is isolation provided between temperature input signals?

  Yes. Photocouplers are provided between all temperature input signals, providing electrical separation between the temperature input circuits.

• What are the power consumption requirements?

  Maximum current consumption is 40 mA at 5 VDC and 59 mA at 24 VDC. These values should be included when calculating the expansion-unit power load.

• What are the physical dimensions of CP1W-TS002?

  The unpacked module measures 9.0 cm x 8.6 cm x 5.0 cm. The specified unpacked weight is 250 g.

• Does the module provide analog voltage or current inputs?

  No. CP1W-TS002 is specifically a thermocouple temperature sensor unit. Its four inputs are intended for J-type or K-type thermocouple signals rather than standard voltage or current inputs.
