Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The AS516E-B is the controller element in a Delta control installation. It receives the field signals and control supply listed above and switches or conditions the load within the rated values shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in packaging machines, conveyor transfer cells, small process skids, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Selection notes for Delta AS516E-B
Delta AS516E-B — PLC / CPU module used as the device-level control core in an automation panel, handling logic, timing and communication tasks. The figures below are taken from the specification table on this page for catalog number AS516E-B; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
- Operating temperature: 0...+55 °C (IEC 60068-2-1) — Confirm the revision of the installed unit before a like-for-like replacement.
- Mounting: 35 mm DIN rail (IEC 60715) — Use it as the reference when cross-checking a current-production equivalent.
- Enclosure rating: IP20 (IEC 60529) — Verify it in the project documentation before confirming the order.
- Certifications: CE, UL, cULus — Check this value against the nameplate of the installed unit before ordering.
