din rail timer switch

Who does what on a din rail timer switch request

Buyers searching din rail timer switch usually need a 35 mm rail body, a named timing function, and a written decision about whether the socket is inside the unit price. The equipment side is that hardware plus listed accessories. The service side is ladder design, wire numbers, installation and inspection. Time Delay Relay Sourcing only coordinates the equipment side: we restate the ratings, approach factories that build that configuration, and line up replies so cost lines can be compared. We do not promise that a quoted width will fit an unnamed enclosure.

A request several factories can quote on the same basis names function, timing band, control voltage with AC or DC, contact arrangement and current in A, rail width, socket yes or no, quantity and destination. If one factory answers with a 17.5 mm body and another with 22.5 mm, those are different mechanical fits; we keep the rows separate rather than averaging widths. Wide-range control voltage against a single-voltage coil is the same problem: the price gap is not a quality ranking until both quotes name the same input range.

Cost lines that are commonly excluded until you ask

Two factory numbers for a din rail timer switch often diverge because one quote is a relay only and the other is a relay plus socket, clip and marker strip, or because one includes export packing and the other assumes dock pickup. Ask for those lines in writing. Freight to the destination postal code must be on or off the same basis. Programming software, USB cables and spare bases are extras unless you bundle them. We will flag a missing line rather than invent a landed total.

When two suppliers answer control (input) voltage range differently, we do not pick a midpoint. We ask each factory to restate the published range with AC, DC or both and the frequency. If one plant can only supply 120 V AC and your drawing shows 24 V DC, that refusal stays visible. Heat dissipation, creepage and isolation figures, if you need them, are document requests against the offered model, not family averages. Accuracy percentages without reference conditions are not comparable.
