IBP Board
There are two equivalent and independent transducer measurement (or acquisition)
channels, placed on IBP board, which comprises the connectors to the transducer cables.
For each channel, the signal acquired from the transducer measurement is provided to
the microcontroller of the IBP board. Each acquisition channel is electrically isolated from
the remaining parts of the equipment set, including Rack and Monitor. Thus, each
acquisition channel (isolated circuit) is electrically isolated from the other channel
(isolated circuit) and from the remaining of the IBP board (non-isolated circuit).
The IBP board detects transducer faults and when the transducer is unplugged.
IBP Keyboard Board
The IBP module has two independent buttons placed on the IBP keyboard board, which
are connected to the microcontroller. The IBP Keyboard board connects to IBP board.
