Honeywell 30755306-501 Relay

The Honeywell 30755306-501 Relay is a specialized electro-mechanical relay engineered for precise switching within Honeywell UDC3200 and UDC2500 Universal Digital Controllers. Designed for high-duty cycle applications in industrial HVACR environments, this replacement relay manages terminal outputs to control actuators, solenoids, and contactors. As a critical HVAC control component, it features a 24 VDC coil voltage and a robust contact surface to minimize resistance and heat generation during high-frequency switching. Field technicians rely on this Honeywell 30755306-501 for its exact OEM compatibility, ensuring that PID control loops maintain tight tolerances without mechanical lag. This switching relay is essential for maintaining the operational integrity of 1/4 DIN controllers, providing the reliable physical break required for safety-critical circuits. Whether you are performing routine maintenance or a full system overhaul, utilizing this authentic electro-mechanical relay prevents the communication errors and output failures common with non-spec universal alternatives.

• Precision Compatibility: Specifically designed for Honeywell UDC series controllers to ensure seamless integration with open collector output configurations.
• Industrial Durability: Engineered for high-reliability switching in demanding thermal and electrical environments.
• Optimized Performance: Operates at a 24 VDC coil rating, providing fast response times for sensitive HVACR control systems.
• Direct OEM Fit: Eliminates the need for field modifications, reducing labor time and ensuring system-wide stability.

• Is this relay compatible with both the UDC2500 and UDC3200? Yes, the 30755306-501 is a standard output component listed in the technical manuals for both 1/4 DIN controller models.
• Can I use this to replace a solid-state relay (SSR)? No, this is an electro-mechanical relay. You must verify if your controller logic and wiring supports mechanical switching versus solid-state outputs.
• What is the standard coil voltage for this part? This unit is rated for a 24 VDC coil, which is the standard for these Honeywell digital controllers.
