The PCI bus card for PC-based control technology OPTORE-PCI16STANDARD offers 16 digital inputs and 16 digital outputs with electrical isolation, individually for each channel. The electrical isolation of the inputs is provided by 16 high quality optocouplers with Schmitt trigger function, and for the outputs by 16 reed relays. The inputs are also protected against harmful voltage peaks by protective diodes. Two different input voltage ranges can be set using easily exchangeable, pluggable resistor arrays. The reed relays of the outputs can handle a switching current of maximum 500 mA. The connections of the output relays are fed to the 37-pin D-Sub socket mounted on the slot bracket of the board. The optocoupler inputs are on the 40-pin post connector on the board.A connector routing set, available as an option, allows routing to a 37-pin D-Sub socket with a slot bracket. The pin assignments and the input voltage ranges are identical to the ISA bus card OPTORE-16STANDARD and the PCI Express bus card OPTORE_PCIe16STANDARD, making it easy to switch to PCI or PCI Express.
