The Bently Nevada 133396-01 is an Overspeed Detection I/O Module. It is a component of the Bently Nevada 3500/53 Electronic Overspeed Detection System.
The module provides two independent overspeed detection channels. Each channel has a built-in signal conditioner that amplifies and filters the input signal from a proximity probe. The module also provides a transducer power supply for the proximity probes.
The overspeed detection channels are independent of each other and can be used to monitor two separate machines or two separate shafts on the same machine. The module provides two independent alarm outputs, one for each channel.
The 133396-01 module is a reliable and effective way to protect rotating machinery from damage caused by overspeed.
