Model 1500A High Flow Positive Bias Relay
Model 1500A High Flow Positive Bias Relay
Brand: Fairchild Industrial ProductsThe Rotork Fairchild 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.
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.
