Siemens Building Technology 243-0018 Signal Selector and respiratory irritationThe Siemens Building Technology 243 0018 Signal Selector is a high performance, dual input pneumatic logic device designed to compare two proportional air signals and transmit the higher value to downstream controllers or final control elements. As the direct replacement for RCC 1108, this highest pressure signal selector is essential for optimizing pneumatic control systems that require precise demand based logic, such as multi zone cooling
