THE COMPUTER POWER OFF. ALWAYS TURN COMPUTER POWER OFF BEFORE INSTALLING A BOARD. CONNECTING AND DISCONNECTING CABLES, OR INSTALLING BOARDS INTO A SYSTEM WITH THE COMPUTER OR FIELD POWER ON MAY CAUSE DAMAGE TO THE I/O BOARD AND WILL VOID ALL WARRANTIES, IMPLIED OR EXPRESSED. Manual IIB-24...
TTL level signals. 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).
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. Figure 1-1: Block Diagram Manual IIB-24...
Ordering Guide IIB-24 24 channel isolated input to TTL output board Special Order Higher input voltages can be accommodated by changing the current limiting resistors. Other examples of special orders would be conformal coating, vertical I/O pin header instead of shrouded right-angle etc..
Install jumpers as required for each option (filtering on, or no filtering on inputs) and as appropriate for how the TTL side of the board will be powered following either the Option Selection section of this manual or the suggestions of the SETUP.EXE software program. Manual IIB-24...
I/O card 50-pin header. Filter Jumpers 24 filter selection jumpers labeled FLT0 through FLT23 provide capability to add filtering to each input to eliminate undesired responses to noisy electrical signals and zero crossings of AC inputs. Figure 3-1: Board Image Manual IIB-24...
Screw Terminal Input Connections Each input signal connection is made at two screw terminals labeled “A” and “B”. The input signal number corresponds to an Input Bit number 0 through 23. Figure 4-1: Input circuit diagram from screw terminal connections Manual IIB-24...
