Tekmar Controls 004 Relay

The Tekmar 004 Relay is a heavy-duty DPDT (Double Pole Double Throw) general-purpose relay designed for reliable switching in commercial and residential HVAC hydronic systems. Operating on a 120Vac coil voltage, this electrical component is essential for isolating circuits or controlling multiple loads such as pumps, fans, and valves. The Tekmar 004 features a plug-in wiring base with screw terminals, significantly reducing field installation time and simplifying troubleshooting for technicians. Its compact 8-pin configuration allows for seamless integration into existing control panels where space is at a premium. Built to withstand high-cycle switching, the Tekmar 004 relay ensures clean signal transfer across both poles, preventing voltage drops in sensitive control loops. This 120 volt relay with base is a standard stocked item for contractors managing Tekmar hydronic controls and building automation interfaces requiring robust mechanical switching.

• Dual-Pole Versatility: The DPDT 8-pin relay design allows for simultaneous control of two separate circuits from a single 120V signal.
• Simplified Serviceability: The plug-in relay base allows for rapid replacement without disconnecting terminal wiring, minimizing system downtime.
• High Load Capacity: Rated for inductive and resistive loads, making it compatible with various HVAC switching relay applications.
• Compact Footprint: Designed to fit within Tekmar control enclosures and standard electrical junction boxes.

What are the contact ratings for the 004 relay?
The Tekmar 004 typically handles up to 10 Amps at 120Vac, though actual load should be calculated based on inductive spikes in motor applications.

Can this relay be used with 24V control logic?
No, this specific model is designed for a 120Vac coil. For 24V applications, a different coil voltage variant must be selected to ensure proper pull-in.

Does the base support DIN rail mounting?
The included base is designed for surface mounting with screws, providing a secure vibration-resistant connection for 120Vac relay wiring.
