1 INTRODUCTION & PHYSICAL DESCRIPTION

The CIO-TERM100 and its variant CIO-TERM100/DST are 100-pin screw terminal boards intended for
use with high-density digital I/O boards. Each has two, 50-pin male IDC connectors that accept our
C50FF-# cables. The screw terminals will accept 12 to 22 AWG wire. See Figures 1-1 and 1-2 for board
connector vs. terminal strip layouts.

The board has 14 open mounting positions where 8-pin, 7-resistor Single Inline Packages (SIPs) can be
installed when pull-up (or pull-down) resistors are necessary or desirable. The common terminals on the
SIPs are all common to each other on the board. The board connection point is labeled “POWER”.

Thus, if the POWER point on the board is tied to +5VDC, any SIP installed and jumper-wired to screw
terminals will have those pins pulled high (Figure 1-3).

Alternatively, if the POWER point is tied to Ground, any (and all) installed SIPs resistors will pull their
associated screw terminals to ground.

We recommend using 2.2Kohm resistors for pull-up or pull-down. You can obtain these from us: the part
number is 2.2K*7PU.

NOTE: SIPs are not connected to screw terminals by board etch. After a SIP is installed, you must

install jumpers to each resistor from the screw terminals as required.

Figure 1-3. SIP Installation

Most boards that you would use this terminal board with have SIP locations also. Either location can be
used with equal efficiency. However, it can be useful to have both. If one or m ore digital lines do not
require termination, there is an adv antage to using the resistor locations on the CI O-TERM100 since the
resistors are individually jumpered to each digital IO line.

If you are unfamiliar with pull-up/pull-down resistor theory, refer to the manual for the Digital I/O board.

See Figure 1-4 and 1-5 for schematics of the CIO-TERM100 and CIO-TERM100/DST terminal boards.
