KMC Controls RCC-1502 Relay

The KMC Controls RCC-1502 Relay is a high-capacity pneumatic reversing relay engineered specifically for technical applications requiring professional-grade signal inversion. As a veteran-preferred HVAC pneumatic control component, this unit is the direct replacement for the legacy RCC-1510 model, ensuring seamless retrofitting in existing building automation systems. Factory-calibrated for an 8 PSI crossover point, the RCC-1502 efficiently reverses proportional signals from a primary controller to a downstream pneumatic actuator or valve positioner. The rugged, flame-retardant plastic housing includes an integrated mounting bracket for secure installation in high-vibration environments. Operators can utilize the manual bias adjustment to retard or advance the output by +/- 15 PSI, providing the necessary precision for complex industrial control systems. Maintain peak performance by ensuring a clean, dry supply pressure under the 30 PSI maximum threshold to prevent contamination of the internal logic components.

• Precise Signal Inversion: Engineered to provide a linear reverse output relative to the input signal for accurate dampener and valve modulation.
• Standardized Calibration: Features a factory-set 8 PSI calibration for consistent performance across multiple control loops.
• Enhanced Compatibility: Serves as a direct-fit substitute for the KMC RCC-1510, reducing downtime during system maintenance.
• Field Adjustability: Includes a bias adjustment feature allowing up to 15 PSI of variance to fine-tune building automation responses.
• Durable Construction: Built with UL-rated flame-retardant materials and a compact footprint for tight enclosures.

• Can the RCC-1502 handle supply pressures above 30 PSI? No, the maximum rated supply pressure is 30 PSI; exceeding this limit may damage the internal diaphragm and affect the 8 PSI crossover accuracy.
• Is the mounting bracket removable for in-line installations? This specific model comes with a fixed bracket for stability; for strictly in-line needs, refer to the RCC-1501 specifications.
• How do I adjust the output bias? Use the adjustment screw to retard or advance the signal by up to 15 PSI to match specific field requirements.
