FAIRCHILD - Relays
Model 1500 Positive Bias Relay is designed for applications that require an output pressure that is the sum of a controlled input signal plus a fixed bias. This pneumatic relay provides high output flow at an output pressure that represents the input signal pressure plus a preset bias.
Features
• The output of the relay is the sum of the spring bias, set with the Range Screw, plus a pneumatic input signal. (Po = Ps + K); where Po is output pressure, Ps is signal pressure, and K is the spring constant set by the Range Screw
• Control sensitivity of 1" water column allows use in precision applications
• Large supply and exhaust valves provide high forward and exhaust flows
• Soft supply and exhaust valve seats minimizes air consumption
• A balanced supply valve minimizes the effect of any supply pressure variation
• Aspirator tube design compensates downstream pressure droop under flow conditions
• A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Unit construction allows you to service the Model 1500A without removing it from the line
• Control sensitivity of 1" water column allows use in precision applications
• Large supply and exhaust valves provide high forward and exhaust flows
• Soft supply and exhaust valve seats minimizes air consumption
• A balanced supply valve minimizes the effect of any supply pressure variation
• Aspirator tube design compensates downstream pressure droop under flow conditions
• A separate control chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Unit construction allows you to service the Model 1500A without removing it from the line
