Switching module for a valve controller

摘要

A valve controller assembly includes a first switch that generates a first input signal based on an operational parameter of a control valve, and a docking assembly is communicatively coupled to the first switch. A switching module is removably secured to and communicatively coupled to the docking assembly such that the first switch is communicatively coupled to the switching module when the switching module is secured to the docking member. The switching module includes a first emulation circuit adapted to receive the first input signal, process the first input signal, and output a first output signal that is different than the first input signal.

1. A method of operating a valve controller assembly, the valve controller assembly including a first switch that generates a first input signal based on an operational parameter of a control valve and a docking assembly communicatively coupled to the first switch, the method comprising:
securing a first switching module to the docking assembly such that the first switching module is communicatively coupled to the docking assembly, the first switching module including a first emulation circuit adapted to receive the first input signal, process the first input signal, and output a first output signal that is different than the first input signal; removing the first switching module from the docking assembly such that the first switching module is not communicatively coupled to the docking assembly; and securing a second switching module to the docking assembly such that the second switching module is communicatively coupled to the docking assembly, the second switching module including a second emulation circuit adapted to receive the first input signal, process the first input signal, and output a second output signal that is different than the first input signal and the first output signal; wherein the first switch and the docking member are each fixed to a printed circuit board.
