Lutron PowPak 20 A Receptacle Control Relay Module

The Lutron PowPak 20 A Receptacle Control Relay Module is a radio-frequency (RF) switching solution designed to control 20 A receptacles. It operates based on input from Lutron Pico remote controls and Radio Powr Savr occupancy sensors, utilizing Lutron Clear Connect RF Technology for reliable wireless communication.

This module is also compatible with the Vive hub, enabling a simplified setup process via a web browser on Wi-Fi enabled devices. The Vive hub allows for control and monitoring of all Vive devices and can be added at any time, though system reprogramming will be required.

Note for Replacement: RMJS-20R-DV-B or RMJS-20RCCO1DV-B can replace RMJ-H20R-DV-B.

Note: This module is not intended for the control of permanently installed lighting fixtures.

System Communication

• Operates using Clear Connect RF Technology for reliable wireless communication.
• RF range is 30 ft (9 m).
• Wireless sensors and controls must be located within 60 ft (18 m) line of sight, or 30 ft (9 m) through walls, of the associated control module. The 60 ft (18 m) range is not reduced by a ceiling tile obstruction.

Load Considerations

• Rating: 20 A; no minimum load requirements. Rated to control 20 A receptacles.
• Motor Rating: 1.0 HP (120 V~), 2.0 HP (277 V~).
• Compatible Loads: May be used with, but not limited to, Monitors, Humidifiers, Fans, Printers. Refer to manufacturer's guidelines for acceptable switching methods.
• Incompatible Loads: May NOT be suitable for devices requiring:
  • Shut-down process before power interruption (e.g., computers).
  • Cool-down process before power interruption (e.g., projectors).
  • Programming (e.g., clocks or DVRs).
  • Long warm-up cycles.
• Hazardous Loads: Not for use with loads that present a hazard if automatically energized (e.g., heaters).
• Receptacle Marking: Any receptacles controlled by an automatic control device must be marked with "Controlled" on the outlet where visible after installation, as per 2017 NEC Article 406.3(E). Labels with this marking are included.

Key Design Features

• LED status indicator illuminates when a button is pressed and turns off 2 seconds after the button is released.
• Power failure memory: Connected receptacles return to their state prior to power interruption.

Contact Closure Output (CCO version only)

Provides occupancy status to third-party equipment such as building management systems, HVAC, and VAV controllers. It offers both normally open (NO) and normally closed (NC) dry contacts with a maintained output type.

• CCO Terminals: Accept 20 AWG to 16 AWG (0.5 mm² to 1.5 mm²) solid or stranded wire.
• Output Type: Latching.
• Voltage/Load Ratings:

  Switching Voltage	Resistive Load
  0-24 V===	1.0 A
  0-24 V~	0.5 A

• Voltage Limit: Not for voltages greater than 24 V---.
• Inductive Loads: The CCO is not rated to control unclamped, inductive loads (e.g., relays, solenoids, motors). For such equipment, a flyback diode must be used (DC voltages only). See diagram below for guidance. For more information, refer to Application Note #434 (P/N 048434) at www.lutron.com.

Diagram Description: A diagram shows the CCO output terminals (NO, NC, COM) connected to an inductive load with a flyback diode in parallel, with a 24 V=== maximum rating indicated.

The system diagram illustrates the module connected to a power source and load. It shows inputs from up to 10 Pico remote controls and up to 10 Radio Powr Savr occupancy/vacancy sensors. The Contact Closure Output (CCO) models can connect to third-party equipment.

Default Operation

Wiring Diagrams

Duplex Receptacle Wiring

The wiring diagram for a standard duplex receptacle shows the module installed in a junction box. The LINE/HOT (Black) and NEUTRAL (White) wires connect to the module. A SWITCHED LINE/HOT (Red) wire exits the module to power the controlled receptacle. An uncontrolled receptacle is also shown. The CCO terminals (NC, NO, COM) are shown for connection to third-party equipment. A note advises not to tie the CCO to ground.

Attention Installer: Receptacles controlled by an automatic device must be marked "Controlled" where visible after installation, as per 2017 NEC Article 406.3(E). Labels are included.

Note: Some applications may require the module to be installed in an additional junction box. Consult Application Note #423 (P/N 048423) at www.lutron.com and local/national electric codes.

Split-Wired Duplex Receptacle Wiring

The wiring diagram for a split-wired duplex receptacle illustrates the module controlling one half of the receptacle. The LINE/HOT (Black) and NEUTRAL (White) wires are connected. The SWITCHED LINE/HOT (Red) wire powers the controlled portion of the split receptacle. The other half of the receptacle remains uncontrolled. CCO terminals are shown for third-party connections, with a note to not tie CCO to ground.

Attention Installer: Similar to the duplex wiring, controlled receptacles must be marked "Controlled" as per NEC Article 406.3(E). Labels are included.

Note: Consult Application Note #423 (P/N 048423) and relevant electric codes for installation details.

Important Safety Notes

⚠️ WARNING: Entrapment Hazard.

To avoid the risk of entrapment, serious injury, or death, these controls must not be used for equipment not visible from every control location or that could create hazardous situations like entrapment if operated accidentally.

⚠️ WARNING: Fire Hazard.

To avoid the risk of fire, serious injury, or death, these controls must not be used for equipment not visible from every control location or that could create hazardous situations like fire if operated accidentally.

Examples of unsuitable equipment include motorized gates, industrial doors, and space heaters. It is the installer's responsibility to ensure controlled equipment is visible from all control locations and is suitable for connection. Failure to do so could result in serious injury or death.
