The E5DC-QX2ABM-000: Outputs are two relay contacts and a voltage output for driving an external solid-state relay — enough for a heating/cooling split or alarm plus SSR. Power supply is 100-240VAC. Termination is spring-clamp, no screwdriver needed.
The closest peer for functional comparison is the panel-mount E5CC-CX2ASM-804. Both accept the same input types and ranges, both have dual relay outputs plus a voltage SSR drive, and both run at 100-240VAC. The critical difference is mounting: the E5DC snaps onto DIN rail; the E5CC requires a panel cutout (45mm square) and uses screw terminals. The E5CC is rated IP66 (washdown-capable); the E5DC is IP20 — fine for an enclosure, not for wet locations. If your cabinet already has the cutout and you need IP66, stay with the E5CC. If you're populating a DIN-rail panel and don't need analog retransmission (the E5CC offers an analog output, the E5DC does not), the E5DC is the right fit.
