Figure 13-5: DO Card Wiring & Cabling Diagram
In the VR-2736A, you have two methods of common wiring signal of
8xDO relays:
 COM1, it is protected by auto-resettable fuse in case of any short
circuit of DO side. This auto-resettable fuse can handle up to 60V
between contacts of DO relays. For setup this you must strap J2
and J3.
 COM2, it is protected by 8A Fuse, but it is not auto-resettable, in
case of any damage caused by short circuit you must replace the
fuse on the card. For setup this type you must strap J2 and J3.
 Independent COM1 & COM2, in this case two channels of CH1,
CH2 can be protected by auto-resettable fuse by COM1, and
CH3~CH8 outputs with COM2 via main execution relay with 8A
fuse. For setup this you must strap J2 and un-strap J3. For
example if you want to have internal test relay circuit, so test rely
used for CH1,CH2 by independent common signal of field.
