Lowest Pressure Signal Selector

The 243 Lowest Pressure Signal Selector is a dual input, single output logic device for use in pneumatic control systems. Application: The 243 Lowest Pressure Signal Selector is used where two input air signals must be compared and the lowest of the two signals transmitted to another logic or fi nal control device. The 243 Lowest Pressure Signal Selector can also be used as a direct acting amplifying relay. Features: Small, lightweight Can be mounted in any position Can be supported by the 1/4-inch (6 mm) poly tubing connected to the input and output fi ttings Can be used as volume amplifying relay Cascade multiple selectors for more than two inputs
