Hardware Specifications

Omron Backplane Bus Velocity & Real-Time Logic Execution

The CP1W-TS101 module interfaces directly with CP1H, CP1L, and CP1E CPU units through the dedicated expansion backplane bus. Internal analog-to-digital hardware converts RTD resistance inputs into 16-bit binary data (4-digit hexadecimal) within a deterministic 250 ms scan cycle across all active channels. Galvanic separation via photocouplers shields CPU logic from field-side ground loops and noise interference. Fixed internal current draws of 54 mA at 5 VDC and 73 mA at 24 VDC optimize power allocation on the main CPU expansion bus during continuous operation.

Field Installation Guidelines

• Subrack Mounting: Snap the CP1W-TS101 unit securely onto a 35 mm DIN rail adjacent to the CP1 CPU or neighboring expansion module, ensuring the bus connector locks into the preceding unit.
• RTD Wiring Strategy: Connect 3-wire Pt100 or JPt100 RTD sensors to the removable terminal block, ensuring lead wire resistance is balanced across all three terminals to eliminate measurement bias.
• Shielding Standards: Route signal cabling using overall shielded 3-conductor wire, grounding the braid shield at a single panel earthing point using 360-deg grounding clamps.
• Grounding Requirements: Wire the functional earth (FE) terminal on the expansion rack directly to a dedicated copper ground bar with a resistance measuring under 100 Ohms.

Frequently Asked Questions

• Is hot-swapping supported for the CP1W-TS101 module on active CP1 PLC racks?

  No. Main system power must be completely disconnected before attaching or removing the CP1W-TS101 expansion module to prevent damage to the backplane bus.

• What temperature sensor types are compatible with the CP1W-TS101 module?

  The unit is designed exclusively for platinum resistance thermometers, supporting standard Pt100 and JPt100 3-wire RTD sensor configurations.

• What is the conversion cycle time for sampling 4 active temperature channels?

  The internal analog conversion logic updates all configured channels within a fixed cycle time of 250 ms for 2 or 4 input points.

• How is converted temperature data formatted within the allocated CPU words?

  Converted readings are written into the 4 allocated CIO input words as 16-bit binary integers represented in 4-digit hexadecimal format.

• What degree of electrical isolation exists between field inputs and internal logic?

  Photocoupler isolation is provided between all temperature input terminals and internal backplane circuitry to prevent ground loop propagation.

• What power supply rails are required from the CPU backplane bus?

  The module draws 54 mA maximum from the internal 5 VDC bus rail and 73 mA maximum from the internal 24 VDC auxiliary power rail.

• What overall measurement accuracy can be expected during operation?

  Measurement accuracy is rated at the larger of +/-0.5% of the converted value or +/-1 deg C, plus or minus 1 least significant digit maximum.

• What storage conditions are specified for spare CP1W-TS101 units?

  Uninstalled spare modules must be stored in original anti-static packaging in ambient temperatures between -20 and +75 deg C in non-condensing environments.
