KMC Controls RCC-1000 Series Relays

RCC-1000 Series

     Pilot capacity reversing relays designed for reversing a proportional signal from a controlling device. Factory adjusted to decrease branch line pressure as the input pressure increases. Comes with a bias adjustment and two factory calibration points (8 and 9 psi).

     Averaging relays designed for applications that do not require large amounts of output air volume. Suitable for room or zone applications such as VAV terminals. Use where desired output signal to the controlled device is to be the average of two source signals.

     Low pressure selector relays are designed to control the final device from the lowest of two pneumatic signals. Can also be used as a signal repeater.

     High pressure selector relays are designed to select the greatest of two pneumatic signals to control the final device. These signals must be supplied from “relieving” type devices like thermostats, receivercontrollers, etc.

     Adjustable diverting/switching relays are SPDT devices and divert one signal to either of two branch circuits or select one of two inputs and transmit it to another control device. They can also be used to feed or exhaust a circuit.

     Signal repeater relay, typically used for Trane VAV boxes with CSC- 2000 series.
