The TSI Card 3500/53 can be used to form a 2-out-of-2 or 3-out-of-3 voting system. It is a highly reliable and fast-responding redundant overspeed protection system specifically designed for mechanical applications.

Each channel of the 3500/53 TSI Card can be programmed using the 3500 configuration software to perform various functions, including:

•  1. Radial vibration, axial displacement, differential expansion, eccentricity, REBAM acceleration, and velocity monitoring.
• 2. Shaft vibration within an acceptable circular area.

The three-channel overspeed protection system provides three independent speed monitoring channels. In the event of an alarm, the three-channel overspeed protection system can be configured to provide a 2-out-of-3 voting function. With this feature, alarm outputs from each 3500/53 module are compared, and the relay will only be driven if the two modules are in agreement.

It should be noted that the channels of the monitor are programmed in pairs and can simultaneously perform multiple functions. Channels 1 and 2 can perform one function, while channels 3 and 4 can perform another (or the same) function.
