Configuring the Auxiliary Input/Output Card
The only configurable items on the Aux I/O Card are the card’s address and 50/60-Hz
timing selection. Since the system may have up to six Aux I/O Cards, the card’s address
selection switches are used to set the Aux I/O Card number. The bank of dip switches used
for this is labeled SW1, located at the bottom of the card’s legend plate. Table 23 shows
the allowed switch settings that result in valid card addresses. Setting switches 1-3 in any
combination not shown in Table 23 will disable the card.
Table 23: Auxiliary Input/Output Card, Address Switches
Switch 4 of SW 1 is used to select 50 Hz or 60 Hz timing if input #39 is used for line input
timing (see the following table).
Table 24: Auxiliary Input/Output Card, Frequency Switch
The factory configuration and field programming documentation refers to the inputs and
outputs as pure numbers, without regard to the Aux
I/O Card on which they belong. The outputs are numbered from 1 to 72. The inputs are
numbered from 1 to 240. Use Table 25 and Table 26 to convert between the system I/O
numbers and Card I/O-Card Address numbers.
