AS-Interface field module with 4 PNP inputs
The Siemens 3RG9001-0AA00 is a digital input module for the AS-Interface fieldbus, providing 4 PNP inputs (D0–D3) via M12 sockets. It operates on the AS-Interface power rail (26.5–31.6 VDC) and draws up to 120 mA from the bus. The inputs switch at a high-level threshold of 10 V minimum, with a sensor supply that is short-circuit and overload protected.
The module measures 45 mm wide, 80 mm high, and 27 mm deep. The M12 sockets (4 inputs) accept 2- and 3-wire sensors. The yellow LED indicates I/O status; the green LED shows AS-Interface diagnostics. The ID code is 0, and the I/O configuration is standard.
