PCI-IDO Series: 16, 32, and 48 Channel Isolated Solid-State Output Cards

Features

• 16, 32, or 48 individually optically isolated solid-state outputs
• Solid-state design permits high-speed switching and long-life expectancy
• Load voltages up to 60 Volts, current up to 2A
• Lower cost per point than externally-racked solid-state relay modules
• Optically isolated channel to channel and channel to ground
• Universal PCI, PCI-X, 3.3V and 5V compatible (Call for PCI-Express availability)

Specifications

Outputs

• Number of Channels: 16, 32, or 48
• Load Voltage Range: 5V to 60V (Voltage supplied by User)
• Load Current per Channel: 1A max. steady state, 2A pulse (Note: Current may be limited by the cable. Certain ribbon cables limit current to 0.5A.)
• Isolation: Optically isolated Channel-to-ground and channel-to-channel (* see note)
• Switching Time:
  • Turn-On 50µs
  • Turn-Off 5µs, inductive-spike protection via a diode
• Switch Resistance: 0.4Ω when saturated
• Switch Leakage Current: 100 to 300µA
• Power Required: +5VDC @ 245mA (48 bits)

*Note on Isolation: Opto-Isolators and connectors are rated for at least 500V, but isolation voltage breakdowns will vary and are affected by factors like cabling, spacing of pins, spacing between traces on the 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 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. Tolerance of higher isolation voltage can be obtained on request by applying a conformal coating to the board.
