Profile: Acces I/O Products, Inc. supplies a range of analog input, analog output, digital, serial communication, and isolated I/O boards & solutions. We also offer complete systems, integration services and enclosures with a quick turn around on custom projects, including software. Our products are designed for use with PC/104, PCI, Low Profile PCI, EBX, EPIC, USB, Ethernet, and ISA buses as well as distributed & wireless I/O. Our analog input devices are used to convert the electrical data from a sensor or transducer into binary data that can then be used by the computer. The device that converts this data is known as an analog to digital converter (abbreviated ADC, A/D, or A to D). An analog input is a measurable electrical signal with a defined range. The analog input changes continuously in a definable manner in relation to the measured property. This data is very useful for process monitoring, process control, or simple monitoring / data collection and acquisition. Our 104-IIRO-8 isolated digital input & relay output card features 8 optically-isolated, non-polarized CMOS compatible digital inputs accept ±31VDC or AC rms, 8 long-life form C electro-mechanical relays switch up to 1A each and 8 non-isolated TTL compatible inputs.
