Selection Notes

Screw terminals hold a 0.5-2.5 mm2 conductor at a specified 0.4-0.5 N.m torque, which suits panels where field wiring needs to be checked and re-torqued during maintenance. Without status LEDs, this variant keeps the enclosure at its base 100 mm width; choose the LED version instead if per-channel diagnostics at the terminal block are worth the added cost. ATEX, IECEx and UKEX ratings alongside cULus make it usable on the panel side of a hazardous-area installation, not just a general-purpose cabinet.

Applications

Fully modular field wiring for SIMATIC S7-1500 digital I/O in machine and process control panels, including panels in ATEX/IECEx/UKEX Zone 2 hazardous areas.
