Siemens Building Technology 243-0018 Signal Selector handling the inductive loads found

handling the inductive loads found in Trane and American Standard blower sections

ensuring precise motor torque and energy efficiency

A faulty switch typically causes the furnace to short cycle

Technicians should measure the microamp (µA) signal using a multimeter in series with the sensor wire

Siemens Building Technology 243-0018 Signal Selector handling the inductive loads foundThe 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
