Hardware Specifications

PLC Determinism and Backplane Bus Velocity

The CP1W-TS102 expansion interface transfers 16-bit binary RTD temperature values directly across the internal CP-series backplane bus during the PLC cyclic scan I/O refresh window. High-speed backplane velocity ensures 4 allocated input words update deterministically without introducing CPU processing jitter or expanding cyclic execution times.

The modular expansion bus permits scaled I/O density integration by chaining multiple CP1W modules side-by-side using the built-in flat ribbon bus connector. Integrated photocoupler isolation between temperature input channels and CPU logic prevents ground loops and blocks common-mode noise propagation across expansion racks.

Field Installation Guidelines

• DIN-Rail Mounting: Mount the unit on a 35 mm DIN rail (PFP-50N/PFP-100N). Ensure side locking mechanisms lock securely to prevent lateral vibration displacement.
• Backplane Connection: Plug the integrated flat ribbon cable directly into the expansion bus connector of the preceding CPU or expansion module.
• RTD Sensor Wiring: Wire 3-wire Pt100/JPt100 sensors ensuring equal wire resistance across conductors A, B, and b to maintain measurement accuracy.
• Grounding and Shielding: Terminate RTD signal cable shielding at a single point using a 360-deg braid grounding clamp attached to the protective earth terminal.
• Terminal Tightening: Fasten terminal block screws to a torque rating of 0.5 N-m to prevent contact degradation.

Frequently Asked Questions

• What sensor types are supported by the CP1W-TS102?

  The module supports Pt100 and JPt100 platinum resistance thermometers. All 4 channels must be set to the same sensor type.

• How many input channels and CIO words does the module allocate?

  The module features 4 RTD input channels and allocates 4 input words in the PLC memory map.

• What is the analog-to-digital conversion time for all 4 channels?

  The conversion time is 250 ms total for 2 or 4 active input channels.

• What format is used to store converted temperature values in PLC memory?

  Temperature values are formatted as 16-bit binary data expressed in 4-digit hexadecimal.

• What current consumption does the module draw from the expansion bus?

  The module draws a maximum of 54 mA at 5 VDC and 73 mA at 24 VDC from the backplane.

• What isolation mechanisms protect internal CPU logic from field interference?

  Photocouplers provide galvanic isolation between individual temperature input signals and internal CPU backplane logic.

• Can different sensor types be mixed across channels on a single module?

  No, while the unit is switchable between Pt100 and JPt100, the same sensor type must be used across all 4 inputs.

• Is hot-swapping permitted for this expansion module during PLC operation?

  No, removing or inserting expansion units while the base controller is energized is strictly prohibited.
