2 inputs / 2 outputs, IP67 field module
The Siemens 3RG9001-0AM00 is a digital I/O module for AS-Interface field networks, offering 2 PNP inputs and 2 transistor outputs in a single IP67-rated housing. The 2 outputs sink a combined 2 A (DC-12/13 load) and require an external AUX POWER supply of 20 to 30 V DC compliant with PELV (VDE 0106, protection class III) — the AS-Interface bus alone cannot drive the output circuits.
EOL hot — sourcing the spare before it fails
For a line running AS-Interface field I/O, this is the part to buy ahead on — one in the cabinet as a critical spare before the failure, not after.
The module measures 45 mm wide × 90 mm high × 27 mm deep — a slim footprint that fits alongside other AS-Interface slaves on a standard DIN rail. The four M12 sockets are labelled D0 (input), D1 (input), D2 (output), D3 (output), with a yellow LED per I/O channel and a green LED for AS-Interface diagnostics. The IP67 rating means the module withstands washdown environments — suitable for food-and-bev or automotive assembly lines where the I/O is mounted directly on the machine, not in a sealed enclosure.
