Removing IO cards
Once the side screws on the earth brackets are removed, the IO cards can be easily pulled out of the IO card chassis
for replacement.
Inserting IO cards
The DR Graphic recorder has the backplane card fitted inside the IO Card Chassis along with the CPU card. Cards can
be inserted into the IO card chassis through the horizontal guides present inside the IO card chassis as per the
combinations mentioned in the table
. Carefully slide the card back into the case until the fixing
bracket on the right side of the card is in line with the single fixing hole on the side of the IO card chassis. Ensure the
card is pushed fully home. Replace/fit the M3 x 8 earth screws and shake-proof washers, on the side of the case, to
secure the card.
One combination of IO cards installed inside the IO card chassis is shown in Figure 21, Slot A supports only AI cards
and Pulse cards; Slot B supports all the IO cards i.e. Analogue Input, Analogue Output, Pulse Input, Alarm/Relay Output
and DI/DO cards and acts as an universal slot.
