5.7.7 Pro II-OPT-32-24V Rev. E
The input module Pro II-OPT-32-24V Rev. E provides 32 channels of optically
isolated digital inputs.
The input voltage range is fixed to 24V, which is also true for the event input.
The switching time of only 100ns allows the sampling of high-speed digital
inputs.
The module can automatically monitor the edges of input channels, which is
performed with a frequency of 100MHz. With every change, the current input
levels are saved together with a time stamp in a FIFO; up to 511 of those value
pairs (input level and time stamp) can be stored. The FIFO data can be read
and processed.
In addition, one can query whether a positive or negative edge has occurred
at the input channels.
Each channel is optically isolated from the system circuitry and from the other
inputs. The event-input is optically isolated from the system as well.
The channels are single ended and share the same ground potential (ext.
GND), which has to be provided on the D-Sub connector.
