KMC Controls RCC-1106 Selector

The KMC Controls RCC-1106 Selector is a critical component for pneumatic control systems, engineered specifically as a low signal selector relay. This precision-built device continuously monitors two separate pneumatic input signals at ports S1 and S2, automatically selecting and transmitting the lower of two pressures to the output port B. Designed for seamless integration into industrial and commercial HVAC pneumatic systems, the RCC-1106 is essential for high-limit or low-limit control strategies where maintaining the minimum signal is vital for equipment safety and process accuracy. It features an integrated mounting bracket for rapid installation and includes connections compatible with standard 1/4-inch OD polyethylene tubing. This pneumatic relay supports an operating branch pressure range of 0 to 20 PSI and is robust enough to handle a maximum supply pressure of 30 PSI, ensuring stable performance across a wide operating temperature range from 40??F to 120??F.

Key Benefits

• Precision Pressure Selection: High-accuracy internal logic ensures the lower pneumatic signal is prioritized without manual intervention.
• Versatile Mounting: Factory-installed bracket allows for secure attachment in any orientation within control cabinets or on-site equipment.
• Industrial Durability: Engineered for long-term reliability in specialized HVACR environments using high-grade internal components.
• Simplified Plumbing: Clearly marked ports (S1, S2, and B) facilitate straightforward pneumatic piping and troubleshooting for field technicians.

Common Questions

What is the maximum pressure rating for this relay?
The KMC RCC-1106 is designed for a standard 0-20 PSI operating range but can withstand a maximum surge pressure of up to 30 PSI.

Can this be used to select the higher of two signals?
No, this specific model is a low pressure selector. For high-signal selection, you would require the RCC-1108 model.

Are there specific air quality requirements?
Yes, like all precision pneumatic controls, the RCC-1106 must be supplied with clean, dry, and oil-free instrument air to prevent internal clogging and ensure consistent switching performance.
