Contec has developed three new expansion chassis for its computer slot expansion boxes.
These new products—the ECH-PE-DE2-H2B, ECH-PCI-DE2-H2B, and ECH-PCI-DE2-H4B—will be available to order from June 26, 2025.

These new expansion chassis add expansion slots to a PC. These products are the successors to the ECH-PE-DE-H2B, ECH-PCI-DE-H2B, and ECH-PCI-DE-H4B.
The separately available EAD-DE-LPE expansion adapter can also be connected to add PCI Express (x1) slots or PCI bus slots. The power supply input voltage for these new products is 12 to 24VDC, but using an optional switching AC adapter (PWA-160AWD2) enables use with 100 to 240VAC power supply inputs.
