3.4 CIO-ERB24 & SSR-RACK24 CONNECTIONS

PCI-DIO96 boards provide digital I/O in two major groups of 48 bits each (96 total,

but each side of the C100FF-xx cable provides 48 bits). However, many popular

relay and SSR boards provide only 24-bits of I/O. The CIO-ERB24 and

SSR-RACK24 each implements a connector scheme where all 96 bits of the

PCI-DIO96 board may be used to control relays and/or SSRs. This configuration is

shown in Figure 3-4 below. The 24-bits of digital I/O on PCI-DIO96 connector pins

1-24 (base address +0 through +3) control the first relay board. The 24-bits on pins

25-50 will control the second relay/SSR board on the daisy chain and so on up to

100 pins.
