GrowControl™ RD8i+ Intelligent 8-Contact Relay with Switches
GrowControl™ RD8i+ relay: eight independent 10 A dry contacts with manual toggle switches that work even if communication is lost. UL Listed.
Dry Contacts with Manual Toggles
GrowControl™ RD8i+ relays independently operate eight 10 A dry contacts for equipment such as HVAC systems, relay and contactor panels, lighting panels and motor controllers.
They connect instantly to GrowControl™ GCX controllers or to an SXE sensor through the GrowNET™ port for advanced automated control.
Manual Toggles
A toggle switch on each relay forces it on or off by hand, in addition to automatic control.
- Toggles work as long as the relay coils have power.
- Even if the relay's processor is damaged.
- Even if communication with the master controller is lost.
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 relays 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.
