✄ VMICPCI-2335 16-Channel Optically Coupled CompactPCI Digital Output Board with Built-in-Test ✪✄✰✮✄✯❊❘�✄✬❙◗❚❊❘ • 16 optically coupled outputs • High isolation potential — 1.5 kV sustained (channel-to-PCI bus) • Galvanic (channel-to-channel) isolation to 500 V sustained in current sinking mode • 8-, 16-, and 32-bit data transfers • I/O addressing or memory addressing • 300 mA current sinking outputs (open collector) • 50 V maximum output voltage • Supports Built-in-Test • Complies with CompactPCI® specification R2.1 • Single CompactPCI slot • 3U board size with optional 3U or 6U front panel FUNCTIONAL CHARACTERISTICS Board Function: This board has 16 optically coupled outputs. The outputs provide a sustained 1.5 kV of system isolation to the CompactPCI bus backplane. 1 Isolation Voltage : 1,500 V sustained field to Compliance: This board complies with the CompactPCI bus; 500 V sustained channel-to-channel CompactPCI Specification Revision 2.1 maximum.* Built-in-Test: The VMICPCI-2335 supports both PHYSICAL/ENVIRONMENTAL on-line and off-line Built-in-Test (BIT). The contents of the Output Data Registers may be read at Physical Dimensions: 3U CompactPCI board any time, thereby supporting on-line testing. The User Connectors: One 37-pin D-shell connector outputs may be put into off-line test mode by setting bits (female) in the CSR. In the off-line test mode, the open-collector outputs are all disabled. Data patterns may then be Ambient Temperature: 0 to 65 ˚C, operating written to and read from the Output Registers for test -40 to +85 ˚C, storage purposes without affecting the outputs. Humidity: 20 to 80 percent, noncondensing Addressing Scheme: The VMICPCI-2335 board address is assigned by the system BIOS per the Altitude: 0 to 10,000 ft (3,048 m) CompactPCI specification. Cooling: 50 LFM minimum air flow OUTPUT CHARACTERISTICS 1. Voltage sourcing option will limit isolation. See Table 1 Output Configuration: Optically isolated, open collector. The user may use the external voltage pins on Ordering Options byte boundaries. External voltage may be injected on Dec. 22, 1998 800-652335-000 A ABC – D E F byte boundaries to supply power for pull-up resistors.
