The WITIO-PCIe192ULTRA (board name: WASCO-PCIe8296) with PCI Express bus offers 192 digital input / output channels, which can be set to 3.3V or 5V input or output levels using jumpers. The 192 input / output channels can be programmed as inputs or outputs in groups of eight channels each. Each input channel can be interrupted and has a programmable digital filter (0 to 65535μs). In addition, one of 32 32-bit counters or one of two IC units (e.g. period and pulse duration measurement) can be coupled to each input channel via software so that it can also be used as a counter card. For applications in which, for example, PWM or simple, high-resolution pulse generation is required, 8 OC units are available.These can be coupled to the first 8 output channels of each 68-pin SCSI socket. In addition, the WITIO-PCIe192ULTRA has two programmable timers with interrupt triggering and a quartz time base. This PCIe-Bus TTL input and output card is suitable for input and output applications that do not require galvanic isolation. However, if electrical isolation is required, the inputs or outputs can be provided with optocouplers and relays using the KM modules. Provide outputs with optocouplers and relays using the KM modules.
