The RX1i intelligent relay is designed to be plugged into a stan-
dard 120Vac wall outlet mounted on a vertical wall surface.
A screw tab is provided which can be used to x the relay to the
wall outlet preventing accidental disconnection from the recep-
tacle.
Equipment to be controlled is then plugged into the outlet on
the RX1i. When the RX1i is activated, power will be switched to
the outlet on the RX1i from the wall outlet.
Mounting the RX1i Relay
General Notes:
1. Install into a vertical receptacle with the RJ45 connection facing down to maintain enclosure rating.
2. Device is not intended for use with an extension cord.
3. For indoor use and installation only.
Installation Instructions
DANGER Electrocution Hazard
Always un-plug the relay module before servicing or wiring; ensure all power is disconnected. For continued protection against
electric shock plug into grounded outlets only and do not remove the ground pin. Install all electrical equipment and wiring in
accordance with national and local electric codes. For indoor use in dry locations only (0-80% RH non-condensing.) Do not open
the relay; there are no user-serviceable parts inside.
DANGER Risque d’électrocution
Toujours non brancher le module de relais avant l’entretien ou le câblage; assurer l’alimentation est débranché. Pour une protec-
tion continue contre le bouchon de choc électrique dans des prises mises à la terre et ne pas retirer la broche de terre. Installez
tous les équipements électriques et le câblage conformément aux codes électriques nationaux et locaux. Pour une utilisation en
intérieur dans des endroits secs seulement (0-80% sans condensation.) Ne ouvrez pas le relais; il n’y a aucune pièce réparable par
l’utilisateur.
NOTICE:
Plug the relay fully ush into a wall receptacle.
Do not plug the relay into an extension cord.

GrowNET™ Hubs
All GrowNET™ devices are connected using standard CAT5 Ethernet cable with RJ-45 connections.
Devices can be connected directly to the GrowNET™ ports on the bottom of the controller, or through HX8
GrowNET™ hubs. It is typical to simplify cabling by locating hubs centrally in hall ways and rooms allowing
single runs from an 8-port device hub back to a central hub or back to the controller.
HX8 GrowNET ™ hubs expand a single port into eight more ports.
Hubs can be daisy-chained to form a network of up to 100 devices per
GrowNET™ bus. Individually buered port transcievers provide excellent
signal integrity and extended communication strength and range.
Hubs provide up to 1A of power for operating sensors and most relays
directly over the CAT5 cable. A DC jack on the hub provides 24Vdc power
to the ports from the included wall power supply. A terminal block
power option is also available.
Refer to the GCX controller manual for details on adding the device to the system.
Connection to GrowControl™ GCX
DIELECTRIC GREASE
Dielectric grease is recommended on RJ-45 GrowNET™ connections when used in humid environments.
Place a small amount of grease onto the RJ-45 plug contacts before inserting into the GrowNET™ port.
Non-conductive grease is designed to prevent corrosion from moisture in electrical connectors.
• Loctite LB 8423 • Dupont Molykote 4/5 • CRC 05105 Di-Electric Grease
• Super Lube 91016 Silicone Dielectric Grease • Other Silicone or Lithium based insulating grease
NOTICE
GrowNET™ ports use standard RJ-45 connections but are NOT compatible the Ethernet network equipment.
Do not connect GrowNET™ ports to Ethernet ports or network switch gear.

Data registers are 16 bits wide with addresses using the standard MODICON protocol. Floating point values
use the standard IEEE 32-bit format occupying two contiguous 16 bit registers. ASCII values are stored with
two characters (bytes) per register in hexadecimal format. Coil registers are single bit values which control
and indicate the status of a relay; 1 being on and 0 being o.

Exterior Cleaning
Exterior may be wiped with a damp cloth wish mild dish detergent, then wiped dry. Disconnect power be-
fore cleaning the enclosure to prevent electrical shock.
Fuse Replacement
There are no fuses or servicable components inside the RX1i. Do not open the enclosure.
Maintenance & Service
Storage and Disposal
Relays are not activating, no power LED on PCB
Ensure the relay is plugged into 120VAC outlet and the power is on to the outlet.
Relays are clicking but no power to an outlet
Check the status LED to determine if AC power is reaching the line terminal of the receptacle. The red LED is
powered by AC voltage from the line voltage terminal of the receptacle and will only illuminate if voltage is
passed through the relay to the terminal. If the status LED for the receptacle is on, check the equipment by
bypassing the relay.
Troubleshooting
Storage
Store equipment in a clean, dry environment with ambient temperature between 10-50°C.
Disposal
This indsutrial control equipment may contain traces of lead or other metals and environmental contami-
nants and must not be discarded as unsorted municipal waste, but must be collected separately for the
purpose of treatment, recovery and environmentally sound disposal. Wash hands after handling internal
components or PCB’s.
