AC Powered 3-slot base for DL205 and Do-more PLC
To use the DirectLOGIC DL205 or Do-more H2 Series PLC, you must have at least one base unit. A base unit has an internal power supply that converts the input power (110-220VAC or 24VDC) to 5VDC in order to activate the modules installed in the base unit.
In the base unit, the far left slot is called the ‘CPU Slot’. It is used for a CPU or base controller. Optional modules (discrete I/O modules, analog I/O modules, and specialty modules) can be installed in the other slots. For instance, if you pick a base unit with nine slots, you can install up to eight optional modules.
