Expansion Options
The difference between a base unit, extension unit and extension block is described as follows:
쎲
A base unit is made up of 4 components i.e. power supply (for base units with AC power
supply only), inputs, outputs and CPU.
쎲
An extension unit is made up of 3 components i.e. power supply, inputs and outputs.
쎲
An extension block is made up of 1or 2 components i.e. inputs and/or outputs.
It can be seen that the extension block does not have a power supply. It therefore obtains its
power requirement from either the base unit or extension unit.
Hence it is necessary to determine how many of these unpowered units can be connected
before the "On Board" power supply capacity is exceeded.
