The PCI card for control technology OPTOOUT-PCI64EXTENDED offers 64 digital outputs with electrical isolation. The electrical isolation is guaranteed for each channel by special, powerful optocouplers that can handle a maximum switching current of 150 mA. Each output is also protected against harmful voltage peaks and pulses by protective diodes. Interrupt triggers are time-dependent using a timer / counter component (8254, 82C54, 71054) combined with a crystal oscillator. For other control tasks there are 16 digital inputs and 16 digital outputs, which are TTL-compatible, on the card. The optocoupler outputs are connected to the 68-pin SCSI-II socket on the slot bracket of the board and to a 68-pin SCSI-II socket on the board.The TTL inputs and TTL outputs are fed to another SCSI-II socket on the board. The connectors placed on the circuit board can each be routed to a SCSI-II socket with a slot bracket using a connector routing set available as an option.
