The number PWB78434-01 refers to a Bently Nevada 110VAC Input Relay Circuit Board. The "PWB" in the part number stands for "Printed Wiring Board," indicating that it is a specific circuit board assembly.

This module is part of an older, discontinued line of Bently Nevada products, specifically designed for use in their machinery protection systems. Its primary function is to handle AC input signals and control relay outputs.

• Function: It is a relay circuit board that operates with a 110VAC input. It works within the larger Bently Nevada system to receive a signal from a monitor and then activate a relay, which in turn can trigger an alarm, shut down a machine, or perform another control function.

• Component Type: Unlike the more modular 3500 series, this part is a specific circuit board, often part of a larger, dedicated relay module
