KMC Controls RCC-1511/1512 2 to 1 Ratio Relay
2 to 1 Ratio Relay
RCC-1511/1512
RCC-1511 and 1512 are main valve capacity ratio relays designed to provide an output signal in proportion to the input. Each 1 psi change to the input yields a 2 psi change to the output. They are used in pneumatic control circuits when the final control device must be controlled by a signal that is proportionally different from the source signal. A bias adjustment is provided and is factory set for 9 psi out with 9 psi in. The size and light weight make them suitable for in-line mounting and can be in any position.
