Hardware Specifications

Omron Backplane Bus Velocity & Real-Time Logic Execution

The CP1W-TS003 expansion unit interconnects with the CPU base module using the integrated CP-series expansion bus ribbon structure. Cold-junction compensation and 12-bit analog-to-digital conversion occur local to the hardware before digital values are transferred directly into allocated CIO memory registers during cyclic scan refreshing. High backplane transmission velocity maintains low processing latency while preserving deterministic data update cycles across expanded I/O density configurations. Firmware flash synchronization ensures seamless system recognition upon power-up without manual address DIP-switch setup.

Field Installation Guidelines

• DIN-Rail Mounting: Clip the module securely onto a standard 35 mm DIN rail adjacent to the CPU base unit or main expansion rack, maintaining at least 50 mm clearance above and below for ventilation.
• Bus Interconnection: Plug the integrated expansion bus cable directly into the CPU or preceding expansion unit's side expansion port prior to applying system power.
• Thermocouple Wiring: Connect thermocouple field wires directly to the screw terminal block using specified extension/compensating wires matching the sensor type (K or J).
• Shielding & Grounding: Use continuous shielded thermocouple extension cable with 360-deg braid shields terminated directly to the control panel earth ground bus bar with resistance under 100 Ohms.

Frequently Asked Questions

• Is hot-swapping supported for the CP1W-TS003 module on CP-series expansion buses?

  No. System power must be turned off completely before connecting or disconnecting the expansion bus ribbon cable to prevent hardware damage.

• What digital resolution does the A/D converter yield for temperature values?

  The internal analog-to-digital converter provides 12-bit binary resolution, delivering 0.1 deg C measurement increments per conversion bit.

• Does the CP1W-TS003 accept standard linear current or voltage analog signals?

  No. The CP1W-TS003 is dedicated to thermocouple inputs and does not support direct linear 4-20 mA or 0-10 VDC analog inputs.

• How is operational power supplied to the CP1W-TS003 module?

  The module derives its operating power directly from the 24 VDC bus of the connected CPU or power expansion unit via the bus ribbon cable.

• What thermocouple sensor types are compatible with this input unit?

  The unit accepts standard Type K and Type J thermocouple temperature sensors wired directly to the front terminal connections.

• What grounding resistance must be verified during system commissioning?

  The functional ground connection must be bonded directly to panel earth ground with a total measured earth resistance under 100 Ohms.

• What cable shielding procedure is recommended for field sensor lines?

  Thermocouple wiring must run through twisted-pair extension cables with 360-deg braid shields clamped to the control panel earth ground.

• What environment conditions are required during non-operating storage of spare modules?

  Uninstalled spare units must remain stored in sealed anti-static bags at ambient temperatures between -20 and +75 deg C non-condensing.
