104-IDI-48AC - 48 In Digial I/O

System
Environment	Operating Temp: 0° to +70°C, (-40 to +85°C Optional) Storage Temp: -55 to +150°C Humidity: 5% to 95% RH, without condensation Board Dimension: PC/104 format, 3.550" by 3.775"
I/O Chipset	Number of inputs: 48 Type: Non-polarized, optically isolated from each other and from the computer. (CMOS compatible) Voltage Range: 48A: Logic Low: 0 to 1.5 VDC or AC rms (40 to 10,000 Hz) Logic High: 3 to 31 VDC or AC rms (40 to 10,000 Hz) 48A: Logic Low: 0 to 5 VDC or AC rms (40 to 10,000 Hz) Logic High: 11 to 60 VDC or AC rms (40 to 10,000 Hz) Isolation: Opto-isolators and connectors are rated for at least 500V channel-to-ground or channel-to-channel, 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 60 VDC 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
IR Interface	Interrupts: Software controlled with jumper IRQ selection (models 104-IDI-48AC and 104-IDI-48BC)
Power Consumption	+5VDC @ 300mA typical
