WattNode® Pulse – Options

The WattNode® Pulse and WattNode Revenue Pulse meters are available with several factory options at an additional charge.

These options apply to the following two families of WattNode meters with a pulse output:

See the WattNode Pulse – Model Selector tool. It builds a full model number with options, validates the options, and provides help.

Option P3 – Per-Phase Outputs

(Not available on WattNode Revenue Models)
Option P3 provides three separate pulse output streams, one pulse output channel per measurement phase, which can be used to monitor each phase of a three-phase circuit independently or to monitor three separate single-phase circuits with one WattNode meter.

  • Option P3 is fully documented in the main WattNode Pulse Manual.
  • Example part number: WNB-3Y-208-P Opt P3

Option PV – Photovoltaic

(Not available on WattNode Revenue Models)
Option PV (Photovoltaic) measures net house energy (to or from grid) and PV or wind generated energy with a single WattNode meter.

Option Hz – Custom Pulse Frequency

Option Hz replaces the standard 4.00 Hz full-scale output pulse rate with a different rate.

  • Frequency range (Standard Bidirectional Outputs): 0.01 Hz to 600 Hz
  • Frequency range (Option DPO, Option P3, Option PV): 0.01 Hz to 150 Hz
  • Example part number: WNB-3Y-208-P Opt Hz=300
  • Example part number: WNB-3Y-208-P Opt P3,Hz=10/20/150

Option DPO – Dual Positive Outputs

Option DPO (Dual Positive Outputs) adds an extra pulse output channel for positive real energy. This allows the WattNode meter to be easily connected to two different devices, such as a display and a data logger.

Option SSR – Solid State Relays

Option SSR (Solid State Relays) replaces the standard optoisolators with solid state relays.

Option PW – Pulse Width

Option PW allows a fixed output pulse width, useful when driving certain devices like electro-mechanical displays.

  • Example part number: WNB-3Y-208-P Opt PW=100. This would result in pulses with 100ms width (conducting or closed).
  • Manual Supplement 17 (PDF)

Option Kh – Watt-Hours Per Pulse

Option Kh combined with Option CT configures the meter for a certain “watt-hours per pulse” value.

  • Example part number: WNB-3Y-208-P Opt Kh=100,CT=50. This would result in one pulse per 100 watt-hours or one pulse per 0.1 kWh.

Option CT – CT Rated Amps

Option CT (used with Option Kh) configures the current transformer rated amps. This is necessary with Option Kh.

Option 2N1 – Two Single-Phase Outputs And One Sum of Phases Output

(Not available on WattNode Revenue Models)
With Option 2N1, one model of WattNode Pulse meter can be used for monitoring either two single-phase circuits or one multi-phase circuit, simplifying ordering, stocking, and installation.
