Product details

The 6ES7556-1AA00-0AB0: I²t rating of 0.17 A²·s affects the inrush current your 24 V DC supply must handle at power-up – use this value to size the supply's transient protection or to coordinate with a fuse. The module consumes 3.3 W typical, so a standard Class 2 supply is adequate for the module alone.

Mounts on 35 mm DIN rail horizontal; 147×35×129 mm. 24 V DC power; status LEDs RUN, ERROR, MAINT, LINK. I&M0–I&M3 asset tracking.
