● PCI Bus

● Number of inputs: Eight

● Type: Non-polarized, optically isolated from each other and from the computer (CMOS compatible)

● Voltage Range: 3 to 31 DC or AC Rms (40 to 10000 Hz)

● Isolation: 500V*(see note) channel-to-ground or channel-to channel

● Input Resistance: 1.8K ohms in series with opto coupler

● Filter Response Times: Rise Time = 4.7 mS / Fall Time = 4.7 mS

● Non-Filter Response Times: Rise Time = 10 uS / Fall Time = 30 uS

***Notes on Isolation: Opto-Isolators and connectors 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 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 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 voltages do not connect the hot side of the line to an input. Tolerance of higher isolation voltage can be obtained on request by applying a conformal coating to the board.
