Wall, In-Line or Panel Mounted Load Analyzer Relay, 7 input
Overview
A diaphragm logic pressure selector selects the highest/lowest branch pressure input from zone thermostats to operate final control elements in pneumatic control applications. Replacements available for Johnson, Powers, Robertshaw, and Barber-Colman.
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.
