AC Powered expansion unit for DL405 PLC
The expansion units are only necessary when you want to use local expansion. They are installed in the CPU slot of the expansion bases. They appear very similar to CPUs, but they only contain a power supply.
One of the most often asked questions for the DL405 family is, “Does the CPU consume an I/O slot?”
The answer is no.The CPU has a special slot in the base and does not consume any of the available I/O slots. The same is true for Expansion Units (D4-EX and D4-EXDC) and the Remote Slave Units (D4-RS).
- Supply voltage: Internal 110/220 VAC power supply with 24VDC/400mA auxiliary power connector (can be used to power field devices)
- Requires I/O expansion cable D4-EXCBL-1 or D4-EXCBL-2
