KMC Controls RCC-1501 Reversing Relay

The KMC Controls RCC-1501 is a high-performance pneumatic reversing relay engineered to invert proportional signals in HVAC control systems. As a veteran-grade reversing relay, this unit is factory-calibrated for an 8 psi crossover point, ensuring that branch line pressure decreases proportionally as input pressure increases. Designed for in-line mounting, the RCC-1501 features a compact ABS housing that meets UL Flame Class 94 HB standards, making it a reliable choice for tight mechanical spaces where a mounting bracket is not required.

For precise system tuning, the RCC-1501 reversing relay includes a manual bias adjustment capable of shifting the output by +/- 15 psi. This allows technicians to advance or retard the signal to match specific actuator requirements. Operating with a maximum supply pressure of 30 psig, this adjustable pneumatic relay maintains an air capacity of 1,728 scim, providing responsive control for pneumatic dampers and valve actuators. To maintain long-term reliability and prevent pneumatic control failure, always ensure the supply air is clean, dry, and oil-free.

• Precise Signal Inversion: Factory-set at an 8 psig calibration for accurate 1:1 signal reversal in proportional control loops.
• Field Adjustability: Integrated bias adjustment provides +/- 15 psi flexibility to fine-tune output signals for specific field conditions.
• Compact Design: Lightweight ABS construction optimized for in-line mounting, reducing installation footprint in crowded enclosures.
• High Flow Capacity: Delivers 1,728 scim at 20 psig, ensuring rapid response times for downstream pneumatic components.

How do I adjust the bias on the KMC RCC-1501?
Using a calibrated gauge on the output port, turn the bias adjustment knob to shift the output pressure. The unit allows for a range of +/- 15 psi relative to the standard 8 psi crossover.

What is the difference between the RCC-1501 and RCC-1502?
Both units feature the same 8 psi calibration, but the RCC-1501 is designed for in-line mounting without a bracket, whereas the RCC-1502 includes a right-angle mounting bracket.

Can this relay be used with non-pneumatic media?
No. This device is designed strictly for clean, dry control air. Exposure to moisture, oil, or other mediums will lead to premature component failure.
