Siemens's Space-Saving I/O Blocks
Siemens Energy & Automation's new ET 200eco PN Ethernet I/O blocks are the latest addition to its Simatic ET-200 distributed I/O product line. The IP67-rated, machine-mount I/O blocks measure only 30 mm in width for eight I/O points, enabling installation closer to controlled devices and directly connected using standard M12 cord-set connectors, saving significant machine wiring and manufacturing cost. They're available in 8-pt and 16-pt digital I/O models, and support industry standard Profinet Ethernet protocol. Also included is a built-in two-port Ethernet switch compatible for multi-drop bus networks or star configuration networks. ET 200eco PN Ethernet I/O blocks support 100Mbit/sec full-duplex transmission speed, and are certified with industry-standard agency approvals, including cUL US, CE, and C-Tick.
