Real-World Scenarios

How Barix R6 solves specific industry challenges.

Heavy Load Switching via Modbus

An industrial controller needs to switch 6 mains-voltage (250V/16A) loads remotely. Barix R6's six high-rated relays handle motor starters, heating elements, and industrial solenoids that standard I/O modules cannot switch directly — controlled via simple Modbus RTU commands.

Remote Lighting Control Extension

A facility manager needs low-cost relay extension to add 6 lighting circuit control points to an existing BMS. R6's small form factor installs in ceiling void junction boxes near the lighting circuits, eliminating long relay cable runs back to the main panel.

Generator Changeover Automation

A UPS installation needs 6 relay outputs for mains/generator changeover sequencing. R6's 250V/16A relays handle the high-current changeover duty while power savings mode extends runtime when the controller is on UPS power — cost-effective relay expansion for critical power applications.
