KMC RCC-1010 Adjustable Ratio Relay

Previous Page

The KMC RCC-1010 is an adjustable ratio relay designed for sequencing pneumatic control components in HVAC systems.

The RCC-1010 can reduce the rate at which a pneumatic device responds to a control signal. This ratio may be adjusted on a percentage basis from zero to 100% (1 to 1). This feature reduces instability in a final control device by effectively increasing the proportional band of the circuit.

Additionally, the device output can be biased in a positive direction to increase the output of the relay. This allows the ratio operation to begin at a specific pressure, such as the start point of a pneumatic actuator.
