FOXBORO继电单元C0135YW描述
继电器是气动放大器。与其电子对应物一样，继电器的功能是将输入信号（气压信号）的微小变化转换为输出信号的大变化。通常，输入中的7kPa或1psi变化将在输出中产生大约80kPa或12psi的变化。
空气供应通过安装继电器的仪器表面上的端口进入继电器。 输入信号（喷嘴压力）通过另一个端口进入继电器并作用在隔膜上。由于隔膜与阀杆接触，两者一致地移动。
当输入信号增加时，阀杆推动球阀，球阀又移动扁平弹簧，允许供应空气进入继电器主体。阀杆的进一步运动使其关闭排气口。因此，当输入压力增加时，阀杆（排气）阀关闭，供应阀打开; 当输入减少时，阀杆打开，供应阀关闭。这改变了输出的压力。
A relay is a pneumatic ampliflier.Like its electronic counterpart,the function of the relay is to convert a small change in the input signal (an air pressure signal) to a large change in the output signal. Typically a 7kPa or 1psi change in the input will produce approximately an 80kPa or 12psi change in the output.
The air supply enters the relay through a port on the surface of the instrument on which the relay is mounted. The input signal (nozzle pressure) enters the relay through another port and actsm on the diaphragm. Since the diaphragm is in contact with a stem valve, the two move in unison.
As the input signal increases,the stem pushes against a ball valve which in turn moves a flat spring, allowing the supply air to enter the relay body. Further motion of the stem valve causes it to close off the exhaust port.Thus,when the input pressure increases,the stem (exhaust)valve closes and the supply valve opens;when the input decreases, the stem valve opens and the supply valve closes. This varies the pressure to the output
