Important Notes

The D4-450DC-1 requires 24 VDC external power; it is different from the AC-powered D4-450 and 125 VDC D4-450DC-2.
This model is discontinued; AutomationDirect lists D4-454DC-1 as a replacement.
The CPU includes a battery, so battery condition should be checked on used/old-stock units.
Confirm the PLC base, memory configuration, communication requirements, and installed specialty modules before replacement.
Follow proper ESD precautions when handling the CPU.
