GrowControl™ CX3i Intelligent 3-Contact High-Amp Relay
GrowControl™ CX3i high-amp contactor: three 20 A dry contacts for single- or three-phase switching of motors, heaters and other high-current equipment.
High-Amp Contactor
GrowControl™ CX3i is a high-amp contactor for motors, heaters and other high-current equipment.
It works as a single-output three-phase contactor or as three individual output contacts, and connects to GrowControl™ GCX controllers through its GrowNET™ port for advanced automated control.
Three-Phase Contactor
Switch a three-phase motor or heater as one output.
Three Independent Contacts
Or use the three 20 A contacts as individual outputs.
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 contact.
- Rugged metal enclosure for wall mounting.
- Durable heavy-duty relay contacts and terminals.
- 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.
Connect it
Use it with a GrowControl™ GCX, or with PLCs and building automation over MODBUS.
GrowControl™ GCX
Part of a complete facility control system on a GCX cultivation controller.
