Wire Sizes and Lengths for the RP-C 230 V Controller Models

This section provides recommendations on wires sizes and lengths for the RP-C 230 V controller models.

This applies to the following RP-C 230 V controller models:

  • RP-C-16A-F-230V, RP-C-16B-F-230V, and RP-C-16C-F-230V

Para obtener más información, consulte RP-C Models .

The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.

Aviso

Screw terminal number 3 differs between different hardware versions of the controller model RP-C-16A-F-230V. Para obtener más información, consulte Differences Between RP-C Hardware Versions .

  1. Use wires rated for at least 75 °C (167 °F).
  2. Not available on RP-C-16C-F-230V.
  3. Only available on RP-C-16C-F-230V. EXT Input is used for connection of an external power supply (24 VAC / VDC) to SSR outputs.
  4. Digital or counter inputs.
  5. Supervised, voltage, current, resistive, or 2-wire RTD temperature inputs.
  6. Confirm the voltage drop from the external load current and the wire resistance (the product of the wire size and length) to obtain the appropriate voltage arriving at the controlled field device (load), to reliably energize and maintain the control action.
