Wall, In-Line or Panel Mounted Load Analyzer Relay, 7 input

A diaphragm logic pressure selector selects the highest and/or lowest branch pressure input from zone thermostats to operate final control elements in pneumatic control applications. Replacement devices are available for Johnson, Powers, Robertshaw, and Barber-Colman devices.

Features

• Seven input manifold containing logic diaphragm, air filter, and restrictions.
• Ten sharp barb connectors for all piping requirements.
• Large integral filter assures clean air to the manifold.
• Requires no field adjustment, and plastic construction results in minimum maintenance.
• Two analyzers can be connected together to increase inputs to twelve.
