Single-width S7-400 module, 25 × 290 × 210 mm (W×H×D). IP20 protection. Power drawn from the backplane: 5 V DC, 1.8 A typical, 9 W dissipation. Three RJ45 ports on the front — two with fixed 100 Mbit/s, one auto-negotiating 10/100. No physical port blocking is included (that feature is available via software lock, but the hardware lacks a switch-off). Mount in the rack and connect via standard patch cords. The module supports up to 14 active connections per CPU and up to 128 connections in multi-CPU systems; per PG access limited to 2.","metaTitle":"Siemens 6GK7443-1RX00-0XE0 CP 443-1, 3×RJ45","metaDescription":"Siemens CP 443-1 communication processor (6GK7443-1RX00-0XE0) with 3 Industrial Ethernet interfaces, DCP/NTP support, compact S7-400 single width.
