Relays and Control Modules

R432 Series (2372 Series)

The pressure selector relays are designed for use in pneumatic control systems where the application requires the comparison, selection, and transmission of the higher or lower of two proportional signals. R432-11 can also be used as a booster relay.

R503 Series (2353-5xx Series)

The R503-1 and R503-2 diverting relays are snap-acting devices with adjustable setpoints. They are designed for a variety of switching and interlocking functions in pneumatic control systems where the application requires one or more of the following functions: feeding and exhausting branch...

R504 Series (2354 Series)

The R504 Series diverting relays are snap-acting devices designed for a variety of switching and interlocking functions in pneumatic control systems where the applications may require one or more of the following functions: feeding and exhausting branch lines, diverting a supply line to either...

R516 (2360-501)

The reversing relay is a proportioning device designed for use in pneumatic control systems where the application requires the reversing of a proportional signal from a controlling device. The R516 branch line pressure decreases in direct proportion to an increase in input signal pressure and...

R539 (2378-501)

The amplifying relay is a proportioning device designed for use in pneumatic control systems where the application requires the amplification of a proportional signal from a controlling device. The relay’s branch line pressure output increases as a 2:1 ratio to the input signal pressure (up to...

R540 (2376-501)

The averaging relay is a proportional device designed for use in pneumatic control systems where the application requires operation of a final control device, or some other control action such as resetting a receiver controller, by the average of the signals from two pneumatic devices. The...

RCC-1000 Series

RCC-1001/1012/1101/1112
     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...

RCC-1010

The RCC-1010 is an adjustable ratio relay designed for sequencing pneumatic control components in HVAC systems. It 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 on up to 1 to 1. This feature can be used to...

RCC-1111

The RCC-1111 multiple input selector relays are designed for selection of the lowest and/or highest of six different pneumatic inputs. They are restricted devices designed for pilot-duty operation. If a large output volume is required, a volume booster relay should be used. For applications...

RCC-1501/1502/1503/1504

These main valve capacity reversing relays are designed for reversing a proportional signal from a controlling device. They’re factory adjusted to decrease the branch line pressure as the input pressure increases. A bias adjustment is provided to retard or advance the output if required. Use...
