Overview

The Dixell Relay 30AMP (RELAY30) is an essential interposing relay designed for licensed fridgies, service technicians, and apprentices who need a reliable 30-amp switching solution. It allows Dixell XR-series controllers to safely manage higher electrical loads, ensuring system integrity and preventing undue stress on the controller's internal components. This simple add-on helps keep installations tidy, compliant, and operating without a hitch.

Specifically engineered as an external 30A interposing relay, the RELAY30 is ideal for use with Dixell XR-series controllers (such as the XR20CX/XR60CX) when the controlled load currents exceed the capacity of the controller's onboard relay. It acts as a robust intermediary, protecting the delicate control circuitry while allowing heavy-duty components like compressors, fans, or defrost heaters to be switched efficiently and safely.

Why It Matters

Controller relays are often not built to handle the significant inrush currents of compressors or the sustained power demands of defrost heaters. The RELAY30 steps in as your system's workhorse, positioned between the controller and the heavy load. It effectively shields the control unit from high electrical stress, allowing the relay's robust contacts to manage the heavy lifting. This crucial protection prevents nuisance trips, extends the operational lifespan of your valuable Dixell controllers, and maintains stable system performance, even in demanding conditions like a steamy Sydney afternoon or a hot rooftop in Brisbane.

What's Included

• ✓ 1 × Dixell Relay 30AMP (Model: RELAY30)

Features & Benefits

• 30A Contact Rating: Provides your controller with the necessary capacity to switch high-current compressor, fan, or defrost loads via an external relay, significantly reducing stress on controller outputs and minimizing costly call-backs.
• Interposing Relay for XR-series: Specifically designed for Dixell XR-series controllers, it's the ideal solution when the controller’s onboard relay is undersized for the application. Wire through the RELAY30 for safe, stable, and compliant operation.
• Simple Two-Stage Control: The controller activates the RELAY30, and the RELAY30, in turn, switches the actual high-power load. This two-stage approach allows for neat panel layouts and streamlined wiring, making installations and servicing easier.
• Field-Serviceable Format: Featuring straightforward terminals and clear markings, this relay is designed for quick and efficient swaps, ensuring minimal downtime when you're working against the clock.
• Broad Application: Highly versatile, suitable for a wide range of uses including coolrooms, freezers, merchandisers, and general HVAC plant where robust external load switching is required.

Applications

• Commercial Refrigeration: Perfect for safeguarding controllers in coolrooms and freezers against high-current loads from compressors and fans.
• Display Cabinets: Ensures reliable operation of merchandisers, handling demanding compressor and fan cycles without stressing the controller.
• HVAC Systems: Utilised in various HVAC plant setups requiring robust external switching of large fans, heaters, or other significant loads.
• Defrost Circuits: Provides reliable, high-current switching for defrost heaters, preventing overload on primary control relays and ensuring efficient defrost cycles.

Tradie Pro Tip

Match Coil/Control Voltage: Always wire the relay coil to suit your panel supply or the controller’s output specifications. If unsure, meticulously check the controller manual and panel drawings to ensure compatibility and prevent damage.

Cable Management: Route all wiring away from heater runs and any sharp edges to prevent potential damage. Clearly label both the coil feed and the switched load so the next technician can perform service efficiently and safely.

Safety First: Prioritize safety by always isolating power and testing for zero energy before commencing any electrical work. Adhere strictly to lockout/tagout procedures and all site-specific Work Health and Safety (WHS) protocols.
