Specifications
Digital Isolated Inputs
- Number of inputs: 16, 32, or 48
- Type: Non-polarized, optically isolated from each other and from the computer (CMOS compatible)
- Voltage Range:
- xxA Logic Low: 0 to 2VDC or AC RMS (40Hz to 10KHz)
- Logic High: 3 to 31VDC or AC RMS (40Hz to 10KHz)
- xxB Logic Low: 0 to 5VDC or AC RMS (40Hz to 10kHz)
- Logic High: 11 to 60VDC or AC RMS (40Hz to 10kHz)
- Isolation: Optically Isolated channel-to-ground or channel-to channel (*see note)
- Input Resistance:
- xxA 1.8K ohms in series with optocoupler
- xxB 15K ohms in series with octocoupler
- Non-Filter Response Times: Rise Time = 10 uS / Fall Time = 30 uS
- Filter Time Constant: 4.7mS
- Power Required: +5VDC @ 300mA typical
*Note 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 60VDC or AC rms. 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.
