What this LOGO! module brings to the panel
The Siemens 6ED1052-1MD00-0BA3 is a LOGO! logic module with an integrated display and push-button interface. It runs on 12 V DC or 24 V DC supply. The I/O complement is 8 digital inputs, of which 2 are usable as analog inputs, plus 4 relay outputs. The relays are rated 10 A with resistive loads and 3 A with inductive loads.
Supply voltage and I/O count — what fits your BOM
Supply voltage is 12 V DC or 24 V DC — no AC supply version, so budget for a DC power supply if the panel runs on 230 VAC. The module draws its operating power from the same DC bus as the inputs. 8 digital inputs, with 2 of those configurable as analog. That means you get 6 dedicated digital inputs plus 2 multifunction channels that can read a 4–20 mA pressure transmitter or a 0–10 V level sensor. The 4 relay outputs are form-A (NO) contacts; each is rated 10 A resistive, 3 A inductive. If your load exceeds 3 A inductive, add a contactor. Depth is 55 mm, height 90 mm — compact enough for a shallow enclosure.
Mounting, approvals, and power reserve
The integrated display and push buttons allow on-site programming and status readout without a laptop. Power reserve is 80 hours — the module retains the program and retentive data for 80 hours after supply loss, so a weekend power outage does not wipe the logic. Approvals include CE, UL, CSA, FM, and marine — covers most industrial, commercial, and shipboard installations. Limit class B for residential-area use. No built-in short-circuit protection on the outputs — external fusing is necessary per the documentation. Budget for a fuse or circuit breaker per output group.
