GrowControl™ RX4i Intelligent 4-Outlet Relay
GrowControl™ RX4i relay: four independently controlled 120 V outlets for pumps, CO₂ equipment, fans and lighting, 6 A each. UL Listed.
Four-Outlet Relay
GrowControl™ RX4i relays independently switch four 120 V receptacles for equipment such as irrigation pumps, CO₂ equipment, fans and lighting trigger cords.
They connect instantly to GrowControl™ GCX controllers or to an SXE sensor through the GrowNET™ port for advanced automated control.
Built for the Job
Flexible and reliable for many applications, built on more than a decade of proven Agrowtek technology.
- LED indicators on the front panel show the status of each outlet.
- Rugged metal enclosure for wall mounting.
- Heavy-duty relays and receptacles.
- Conduit knock-outs and screw terminals for easy electrical installation.
MODBUS RTU
The GrowNET™ port accepts MODBUS RTU commands for PLC control; the internal digital controller operates the relays.
Built-In Diagnostics
The controller logs the total number of contact closures for each relay, and recalls the serial number, date of manufacture, contact count and status.
Power Cord Kit
Connect the RX4i to conduit through the knock-outs on the bottom, or plug it straight into a 120 V wall outlet with the optional cord kit: a 6 ft power cord and a cord grip that installs in the conduit knock-out.
Load Rating
Each outlet is rated 6 A, with 9 A maximum combined across all four outlets.
Connect it
Use it with a GrowControl™ GCX, or with PLCs and building automation over MODBUS.
