Siemens 243-0010 RL-243 Balanced Retard (BR) Relay is a pneumatic auxiliary device used to obtain special pneumatic signal outputs for use in a pneumatic control system. Standard applications include signal retarding, balancing action, and signal advancing. The relay can also be used to obtain several special control functions such as signal hesitation and pressure limiting. (See Figures 2 through 6 on attached Technical Instructions PDF.)

The relay operates on a force-balance principal and is provided with a Powers’ two-valve design to assure stability and prevent unnecessary air consumption. Internal relief assembly prevents signal lock-up and assures fail-safe operation. A single spring adjustment is provided to allow setting the relay for desired operation. The relay is also adaptable for flush panel mounting to facilitate manual readjustment if desired.
