KMC Controls RCC-1009 Diverting Relay

The KMC Controls RCC-1009 is a high-performance pneumatic diverting relay engineered for precise signal management within commercial HVAC pneumatic control loops. As an adjustable SPDT relay, it allows technicians to divert a single air signal into two separate branch circuits or select between two independent inputs to drive a downstream control device. This versatility is essential for managing complex sequencing in air handling units and terminal terminal unit applications. With an adjustable setpoint range of 3 to 23 psi and a maximum pressure rating of 30 psi, the RCC-1009 provides the reliability needed for critical logic functions and air signal switching. Designed as a direct replacement for 2354-101 and AK-40401, this unit ensures seamless integration during system retrofits or repairs. Its robust construction supports an operating temperature range of 40??F to 120??F, making it a staple for any contractor maintaining legacy or modern pneumatic infrastructure requiring accurate pneumatic switching action.

Key Benefits:

• Flexible Logic Control: Functions as a versatile pneumatic SPDT device to switch, divert, feed, or exhaust circuits based on system demand.
• Precise Field Calibration: Features a 3-23# adjustable range with a 5 psi differential, allowing for fine-tuned pneumatic sequencing.
• Broad Compatibility: Serves as a standard KMC Controls replacement part for obsolete pneumatic relays like the 2354-101.
• High Air Capacity: Capable of 432 scim at 20 psi, ensuring fast response times for connected actuators and controllers.
• Durable Construction: Engineered with 3/16-inch connections for 1/4-inch OD tubing to withstand standard industrial pneumatic systems.

Common Questions:

How do I adjust the switching setpoint on the RCC-1009?
The setpoint is field-adjustable within the 3 to 23 psi range using the adjustment screw. Turning the screw alters the pressure at which the internal diaphragm shifts the air signal between the NC (Normally Closed) and NO (Normally Open) ports relative to the Common port.

Can this relay be used to select the higher of two signals?
While the RCC-1009 is a diverting/switching relay, it is primarily used for SPDT logic. For specific high-pressure selection, ensure your piping configuration utilizes the inputs correctly to transmit the desired signal to the output port based on the adjustable setpoint.

What is the maximum operating pressure for this unit?
The KMC Controls RCC-1009 is rated for a maximum operating pressure of 30 psi, though it is typically used in standard 0-20 psi pneumatic branch lines.
