Output supply is drawn directly from the AS-i cable at 24 V DC, eliminating a separate power feed for the output stage. This module is designed for the TUCHENHAGEN form factor, a compact housing common in automotive and material-handling AS-i drops. The 4 PNP inputs are suitable for sourcing-type sensors (e.g., proximity, photoelectric) common on AS-i networks. The 4 outputs at 45 mA each handle small loads such as indicator lamps, solenoid pilot valves, or signal relays — not direct motor or actuator power. Outputs are supplied at 24 V DC via the AS-i yellow cable, which simplifies wiring but limits total output current to what the AS-i segment power supply can deliver. On a standard AS-i power supply (typically 2 A or 4 A), four outputs at 45 mA is well within budget, but if the same segment also powers other modules, the aggregate draw needs checking. The screw terminal connection is field-friendly for maintenance electricians who prefer a screwdriver over a spring-cage tool. It accepts standard ferruled or solid conductors. The TUCHENHAGEN housing is a specific mechanical footprint — verify that the mounting base or profile rail in your panel matches this form factor before ordering. ## Deployment Context This module mounts on an AS-i flat-cable profile rail or a standard DIN rail via an adapter base. It is typically deployed in a control cabinet or junction box near the field devices it serves, reducing home-run wiring back to the PLC. The 24 V DC output supply via the AS-i cable means no additional 24 V DC distribution is needed at the module — the yellow AS-i cable carries both data and power for the outputs.","metaTitle":"Siemens 3RK1400-0CE00-0TB3 AS-Interface Module, 4I/4O","metaDescription":"Siemens 3RK1400-0CE00-0TB3 AS-Interface module with 4 inputs PNP, 4 outputs 45 mA, 24 V DC via AS-i cable, screw terminal.
