Opto Isolators connector and relays are rated for at least 500V but isolation voltage breakdowns will vary and is affected by factors like cabling spacing of pins spacing between traces on PCB humidity dust and other environmental factors This is a safety issue so a careful approach is required For CE certification isolation was specified at 40V AC and 60V DC The design intention was to eliminate the influence of common mode Use proper wiring techniques to minimize voltage between channels and to ground For example when working with AC lines do not connect the hot side of the line to an input Power Required e 5VDC 250mA min 750mA max all relays ON 6 Manual PCI IIRO 16 Environmental Ambient Temperature Operating 0 C to 50 C Storage 40 C to 85 C Humidity 0 to 9096 non condensing Weight Approx 8 oz Size 6 80 long 173 mm Voc Y ISOLATED mmm INPUT 0 ADDRESS AND k CONTROL LOGIC INPUT OUTPUT REGISTERS REGISTER INPUTS 1 14 WITH WITH SWITCHABLE S READBACK FILTERS l CHANGE OF ve STATE Jj DETECT ISOLATED aK EN FILTER ENABLE REGISTER PCI BUS INTERFACE l COMPUTER PCI BUS Figure 1 1 Block Diagram OP2 OP10 OP3 OP11 OP4 OP12 OP5 OP13 OP6 OP14 OP7 OP15 Manual PCI IIRO 16 Chapter 2 Installation A printed Quick Start Guide QSG is packed with the card for your2. anywhere in the 0000h to FFFFh range The card occupies eight consecutive 8 bit registers in I O address space PCIFind uses the Vendor ID and Device ID to search for your card then reads the base address and IRQ If you want to determine the base address and IRQ without using PCIFind use the following information The Vendor ID code is 494F ASCII for I O The Device ID code for the card is OF08 An example of how to locate PCI card resources is provided with in the PCASOURCE directory under your installation directory This code runs in DOS and uses the PCI defined interrupt BIOS calls to query the PCI bus for card specific information You will need the Device ID and Vendor ID listed above to use this code 10 Manual PCI IIRO 16 Chapter 4 Programming The base or starting address is assigned by the computers plug and play operating system during installation and will fall on a eight byte boundary see chapter 3 The card s read and write functions are as follows VO Address Read Write Base 1 Interrupt Clear Base 2 Interrupt Disable Base 3 Filter Disable Base 4 Outputs 8 15 Base 5 Unused Base 6 Unused Base 7 Unused Relay Outputs At power up all relays are de energized normally closed contacts The relay outputs are controlled by writing to the base address 0 and 4 Each bit within the bytes controls a specific relay A 1 energizes the corresponding relay and a 0 de energizes it The stat
