Chapter 1: Installation
The RB-24 Series cards installed external to the host computer. The card is supplied with four
0.375" stand-offs and may be installed on user-supplied panels/chassis. The card provides headers
for both 37- and 50-conductor ribbon cable connection to the host computer and screw terminal
terminations for the relay outputs. Silk-screen labels on the board identify the relay elements to
which they connect. The screw terminals used can accommodate wire sizes as large as #14 AWG.
To ensure that there is minimum susceptibility to EMI and minimum radiation, it is important that
EMI cabling and break-out techniques be used. (cable conected to ground at the aperture of the
digital I/O card that will provide signals, twisted pair wiring, etc.)
Power Connections
Connector J3 is provided for easy application of +5 VDC computer power via a quick disconnect
cable from the computer power bus. Screw terminals are also provided for 5-volt external power to
the card at TB13. (Note: Jumper JP1 must be installed if you intend to apply power through the
screw terminals.) Alternatively, when the AC Power option is installed, JP1 should not be installed
and the AC power is applied at TB13.
The following page illustrates the layout of the RB-24.
