CIO-ERB24 and SSR-RACK24 daisy chain configuration

Many relay and solid-state relay (SSR) racks provide only 24-bits of digital I/O. You can configure the

CIO-ERB24 relay output board and SSR-RACK24 I/O module rack in a daisy chain configuration to use all of

the digital I/O bits provided by the PCI-DIO96 board. An example of the daisy chain configuration scheme is

shown below.

The PCI-DIO96 board provides digital I/O in a group of 96 bits. Each of the C100FF-x cable's 50-pin

connectors provides 48-bits. To use all of the board's 96 digital I/O bits to control relays and/or SSRs, configure

the daisy chain as shown in Figure 7.

Figure 7. PCI-DIO96H to C100FF-x to relay rack daisy chain cabling

The PCI-DIO96 board's 24 digital I/O bits on pins 1-24 (base address +0 through +3) control the first relay

board on the chain. The 24 DIO bits on pins 25-50 control the second relay/SSR board on the daisy chain and

so on, for up to 100 pins.
