Temperature range and derating
The 6AG1055-1MB00-2XB1: This module lives where standard LOGO! units won't: ambient -25 to +70 °C. Under UL/cUL use (File E120869) the max drops to 55 °C. The input voltage range also narrows above 55 °C: 11–27.5 V DC instead of the full 10.8–28.8 V DC. Output relay rating changes too — 3 A resistive per relay above 55 °C (normally 5 A), and inductive loads drop to 1 A per relay above that threshold (3 A below). Keep these curves in mind if you're stuffing this into a hot panel with forced convection.
Compliance conformance for cross-border shipment
The module carries UL recognition (E120869) and is rated Limit class B for residential-area use. No FM, CSA, or marine approval — verify local codes if those are required.
Mounting and wiring field note
Mounts on 35 mm DIN rail, 2 DU wide. Resistive load max 5 A per relay (10 A total), inductive max 3 A; no short-circuit protection — external fusing assumed; inputs: 4 digital, sink/source.
