How it stacks against the E5CC
The E5DC-RX2ASM-002: The E5CC-CX3A5M-004 is a functional peer—same input range, same 3-relay config, same RS-485 protocol—but it's panel mount with an IP66 front, event input, and a 45x45mm cutout. The E5DC is DIN-rail only, IP20. That means no drop-in: different enclosure prep, different mounting footprint. If your panel is already cut for an E5CC, stick with that family; if you're building new on a DIN rail, the E5DC saves panel space and cuts installation labor.
