DL205 Installation and I/O Manual, Rev. B
The DL205 bases each provide different numbers of slots for use with the I/O
modules. You may notice the bases refer to 3-slot, 4-slot, etc. One of the slots is
dedicated to the CPU-slot controller, so you always have one less I/O slot. For
example, you have five I/O slots with a 6-slot base. The I/O slots are numbered 0 – 4.
The "CPU" slot always contains a CPU-slot controller and is not numbered.
The most commonly used I/O modules for the DL205 system (AC, DC, Relay and
Analog) can be used in any slot. The following table lists the valid locations for all
types of modules in a DL205 system.
