GrowControl™ RD8i Intelligent 8-Contact Relay
GrowControl™ RD8i relay: eight independent 3.5 A dry contacts for HVAC, relay and contactor panels, lighting panels and motor controllers. UL Listed.
Independent Dry Contacts
GrowControl™ RD8i relays independently operate eight dry contacts for equipment such as HVAC systems, relay and contactor panels, lighting panels and motor controllers.
They connect instantly to GrowControl™ GCX controllers through the GrowNET™ port for advanced automated control. Eight contacts count as one GrowNET™ device.
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.
