Convenient and Versatile Relays Give You Multiple Options When Controlling Equipment In Your Grow Site
Agrowtek's R Series outlets and relays operate one to 8 receptacles for control of equipment such as irrigation pumps, CO2 equipment, lighting trigger chords, and more! These relays can be configured with Agrowtek's MXC series (using the SXE controller) or if you want to control multiple relays, Agrowtek offers the GCX Cultivation Controller for the ultimate control of your environment.
LED indicators on the front panels provide status of each outlet.
Rugged and durable, there are 4 options to choose from;
- RX1i - 1 120V Outlet
- RX4i - 4 120V Outlets
- RD8i - 8 Dry Contacts
The RX1i is meant to be power by plugging into a 120Vac wall outlet. The RX4i can be purchased with a 120Vac wall outlet, if there is no power cord installed on the RX4i, one may be installed (14AWG minimum) or the RX4i may be directly wired to a 15A circuit breaker using standard 1/2” EMT conduit and fittings. The RD8i comes standard with a 24Vdc 12w power supply, alternatively, 12-24Vdc may be supplied to the RD8i via a terminal block inside the unit. Red LED indicator lights turn on when AC power is activated to the receptacles.
Connects instantly to Agrowtek’s mini controllers via the GrowNET™ port for advanced automated control functions, including the SXE Controller and GCX Cultivation Controller. Use stand-alone with the optional LX1 USB AgrowLINK for PC based control. LX2 ModLINK connects GrowNET™ devices to RS-485 for MODBUS RTU protocol communication.
Setting Up Your R Series Relay
Connect the sensor to the relay using the included cross-over ethernet cable as shown in the diagram. (RX4i shown for example)
Important: ONLY use cross-over adapters provided by Agrowtek. Incorrect cross-over adapters or cables can cause damage to the equipment.

Typical Configuration
Shown in this example is the MCX4. The GrowControl RX4i relay independently operates four receptacles for control of equipment such as: irrigation pumps, CO2 equipment, fans, lighting trigger cords, etc. Connects instantly to Agrowtek's GCX Cultivation Controls or to a SXE sensor via a GrowNET™ port for advanced automated control functions.
LED indicators on the front panel provide status of each outlet. Rugged metal enclosure for wall mounting. Conduit knock-outs and screw terminals for easy electrical installation.
