FUNCTIONAL DESCRIPTION

The IIB-24 optically isolated input board is designed to add capability to interface powered signals originating from equipment with different power sources to eliminate troublesome ground loops and circulating currents. While ADL offers up to 120 buffered digital I/O lines on a single PCI board in 5 groups of 24 for monitoring dry contacts and TTL interfacing, there is often a need to also interface powered status signals. Simply add in an IIB-24 to any 24 bit group and you’ve expanded your signal interface capability without needing to program a new device or find another open PCI slot or USB port.

Less than half the cost of a solid state module mounting rack with discrete input modules, and about a quarter size of the footprint, this addon module will be hard to compete with for applications requiring some level of optical isolation or higher than TTL level signals.

The isolated, non-polarized inputs may be driven by either DC sources of 3-31 V (or higher by special order) or AC sources at frequencies of 40Hz to 10kHz. Optically isolating the digital inputs from each other, and from the computer, assures smooth, error-free data transmission in noisy, real-world environments. The input channels are accessed via screw terminals. The TTL input signals are connected to the DIO product via a 50-pin IDC type right angle header.

The IIB-24 is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board is PC/104 sized (3.550 by 3.775 inches). Easily mount the board on a DIN-rail using our MP104-DIN adaptor.
OEM USB/104 FORM FACTOR

The OEM “board-only” version is perfect for a variety of embedded applications. What makes this approach unique is that its PCB size and mounting holes match the PC/104 form factor. This allows our rugged digital board to be added to any PCI-104 or PC/104 stack.
