● PCI Bus
● 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)
● The “A” version supports simultaneous output across all ports via external rising edge on P2 pin 50
***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.
