Description
The Omron CP1W-TS101 is a dedicated Temperature Sensors Unit designed for the CP-series programmable logic controller platform, providing seamless modular expansion for CP1E, CP1L, CP1H, and CP2E micro CPU base blocks. The primary purpose of this hardware module is to acquire analog temperature data directly from external sensors and convert these physical variations into digital values over the PLC internal extension bus. The hardware is configured with 2 dedicated analog input channels specifically engineered to interface with Thermocouple sensors (Types K and J). It implements internal cold-junction compensation and linear processing to map temperature loops directly into the central processing unit data registers without requiring standalone transmitters. This unit functions as an essential instrumentation element for thermal processing lines, packaging machinery, and commercial panel builds.
Features
- Dedicated thermal processing unit featuring 2 independent thermocouple sensor inputs.
- Native hardware compatibility supporting standard Type K and Type J thermocouple elements.
- Direct micro bus interface coupling for high-speed data transmission to the main CPU.
- Removable screw terminal block assembly for simplified maintenance and field replacement.
- Compact form-factor optimized for localized integration inside industrial control panels.
Applications
- Temperature monitoring zones in industrial heating chambers and laboratory ovens.
- Sealing bar temperature regulation circuits on horizontal packaging machinery.
- Hot-melt adhesive systems and plastic processing equipment.
- Multi-zone food service processing lines and commercial baking machinery.
- Localized HVAC duct tracing and exhaust gas monitoring units.

Installation Guidelines
-
Bus Attachment: Ensure the main controller chassis is fully disconnected from plant power lines before inserting the side extension cable. Securely click the expansion connector ribbon hook into the adjacent unit base interface.
-
DIN Rail Mounting: Mount the expansion module horizontally onto a standard 35mm DIN rail profile inside the control sub-panel. Install rigid side brackets to protect the system against mechanical sliding.
-
Thermocouple Compensation Cable: Use matching, certified compensation or extension wires corresponding precisely to the thermocouple type installed (Type K or Type J) up to the terminal block.
-
Shielding Integration: Utilize twisted, shielded thermocouple cables and terminate the metallic shield braid directly to an isolated functional earth terminal to mitigate environmental EMI.
-
Routing Distance Isolation: Position sensitive thermocouple signal pathways inside separate wire channels completely removed from high-current three-phase distribution lines or variable frequency drive cables.
FAQ
What specific sensor types can be wired directly into this Temperature Sensors Unit?
The unit features dedicated hardware tracking for Type K and Type J thermocouple sensors.
How many analog sensor channels are provided on this interface card?
The module contains 2 independent temperature sensor input channels.
With which Omron PLC families can this expansion unit be paired?
It is fully compatible with standard CP-series micro controllers, including the CP1E, CP1L, CP1H, and CP2E CPU bases.
Does this device include linear analog voltage or current output capabilities?
No, this model features 0 analog outputs and functions strictly as a data acquisition module.
Where can the temperature value registers be read inside the controller logic?
The data outputs are updated automatically and can be read out through designated I/O allocation registers inside CX-Programmer or Sysmac Studio.
Is it necessary to remove the entire unit if a field wire needs servicing?
No, it features a removable screw terminal block mechanism that allows quick maintenance without unmounting the chassis.
Can I mix a Type K sensor on channel 1 and a Type J sensor on channel 2?
The input types must be configured uniformly via the allocation setup parameters according to standard engineering instructions.
What happens if a thermocouple wire breaks or becomes disconnected?
The internal logic flags an open-circuit fault configuration error inside the corresponding data register of the CPU unit.
Does this expansion module require an external 24V DC auxiliary power line?
The system logic parameters and operating currents are fed through the dedicated internal backplane ribbon bus from the CPU block.
Can the module be mounted in a vertical layout?
No, it must be mounted horizontally alongside the main PLC base to allow correct heat dissipation across the ventilation paths.
