KMC Controls RCC-1012 Relay

The KMC Controls RCC-1012 is a high-performance pneumatic reversing relay engineered for precise signal inversion in commercial and industrial HVAC control systems. As a pilot-capacity device, it effectively decreases branch line pressure as input pressure increases, making it an essential component for proportional control logic. This unit is factory-calibrated for an 8 psi crossover point, ensuring reliable switching transitions without the need for immediate field adjustment. Designed for streamlined integration, the RCC-1012 features a compact, in-line mounting configuration without a bracket, allowing it to fit into tight control panels or directly onto 1/4" OD polyethylene tubing via its 3/16" connections.

With a maximum safe operating pressure of 30 psi and an air capacity of 17.3 scim, this relay provides the sensitivity required for complex pneumatic circuits. The RCC-1012 relay includes a built-in bias adjustment (+/- 15 psi), giving technicians the flexibility to fine-tune the output signal to match specific sequences of operation. Constructed with durable materials and weighing only 2.5 oz, it is a lightweight yet rugged solution for reversing proportional signals from thermostats or receiver-controllers.

Key Benefits

• Precision Signal Inversion: Delivers accurate reversing logic for proportional pneumatic controllers.
• Factory Calibrated: Set at an 8 psi calibration point for "out-of-the-box" reliability in standard 8# C-O applications.
• Field Adjustability: Integrated bias adjustment allows for custom offset tuning up to 15 psi.
• Space-Saving Design: Bracket-less, in-line mounting simplifies pneumatic control relay replacement in crowded enclosures.
• High Compatibility: Works seamlessly with 1/4" tubing systems and standard pneumatic air supplies up to 20 psi.

Common Questions

What is the difference between the RCC-1012 and the RCC-1112?
The RCC-1012 is designed for in-line installation without a mounting bracket, whereas the RCC-1112 includes a factory-installed mounting bracket. Both share the same 8 psi crossover calibration and performance specs.

Can the crossover point be adjusted in the field?
While the 8 psi calibration is factory-set, the KMC RCC-1012 features a bias adjustment screw that allows you to shift the output signal relative to the input, providing necessary flexibility for specific sequences.

What are the port designations for this relay?
Standard KMC porting applies: Port M is for the main air supply, Port B is the reversed output signal, and Port S is the input signal from the controlling device.
