KMC Controls RCC-1109 Diverting Relay

The KMC Controls RCC-1109 is a high-performance pneumatic diverting relay engineered for versatile signal management in commercial HVAC systems. This SPDT pneumatic relay is designed to either divert a single pilot signal to one of two branch circuits or select between two separate inputs to transmit to a downstream control device. Operating within a field-adjustable 3-23 PSI pressure range, the RCC-1109 provides technicians with precise control over air system logic, including the ability to feed or exhaust branch circuits based on real-time demand. Built with a rugged nylon body, this unit handles a supply pressure up to 20 PSIG and features a high air capacity of 432 scim, ensuring rapid response times in critical building automation sequences. The inclusion of a robust mounting bracket facilitates secure installation in tight control cabinets or directly on equipment. For contractors maintaining legacy pneumatic infrastructure, the RCC-1109 serves as a reliable switching relay for sequencing HVAC pneumatic controls and optimizing damper or valve actuator operation.

• Versatile SPDT Logic: Seamlessly switches between two branch lines or selects between dual input signals for complex pneumatic sequencing.
• Field Adjustable Range: Features an adjustable setpoint from 3 to 23 PSI, allowing for precise calibration to specific site requirements.
• High Flow Capacity: 432 scim air capacity ensures minimal lag in pneumatic signal transmission and actuator positioning.
• Durable Construction: The nylon body and compact design provide long-term reliability in environments ranging from 40 to 120 degrees Fahrenheit.
• Simplified Integration: Supplied with a factory mounting bracket for fast installation in standard pneumatic control panels.

Can the RCC-1109 be used to exhaust a circuit?
Yes, this relay is designed to divert one signal to either of two branch circuits or it can be utilized effectively to feed and exhaust a circuit depending on your piping configuration.

What is the maximum supply pressure for this unit?
The RCC-1109 is rated for a maximum supply and input pressure of 20 PSIG, with a maximum operating range safety margin up to 30 PSI.

Does this unit replace the RCC-1009?
The RCC-1109 belongs to the same functional family as the RCC-1009 but typically includes the mounting bracket as part of the assembly for easier field installation.
