PCIe I/O Card Connections
Adept Peripherals User’s Guide, Rev A 21
Optional I/O Products
These optional products are also available for use with digital I/O:
• Terminal Block, with terminals for user wiring. Connects to the PCIe connector on the I/O
card in the SmartVision EX or the XDIO port on the SmartController CX. (09438-000)
This manual and the corresponding fold-out sheet assume you will be using a terminal
block.
NOTE: The I/O card is supplied with an HPDB50 - DB50 Cable (09448-020), 2
meters long, for connecting the I/O card to the terminal block.
• DB50 - DB50 Extension Cable, 5 meters long. (09447-050)
Input Signals
The 16 inputs are arranged in two groups. Inputs 1001 through 1008 are independently isolated
and differential. Inputs 1009 through 1016 are grouped into a bank, and all share a single common
source/sink line.
The inputs are accessed through direct connection to the 50-pin connector (see Tab le 4 - 4 on
page 20), or through the optional terminal block.
Input Specifications
The following table applies to all inputs, 1001 - 1016, on the I/O card.
NOTE: The input current specifications are provided for reference. Voltage
sources are typically used to drive the inputs.
