Fairchild - Model M14 -Positive and Negative Bias Relay

Designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias, Fairchild`s Model 14 Biasing Pneumatic Relay provides versatility in its ability to provide either positive or negative biasing in a single unit. The output of the Model 14 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 combined spring constant.
