Siemens 3RK1400-1KG01-0AA1 Programmable Logic Controller Module

Siemens 3RK1400-1KG01-0AA1 is an AS-Interface load-feeder module that provides 24 V DC power to an AS-I network while delivering two digital inputs and one digital output for simple field I/O on a 40 mm or 60 mm busbar system. It is designed for mounting on 40/60 mm carrier systems and can be mounted on standard rails using SIRIUS adapters, occupying a 45 mm module width. The unit is fed by a 24 V DC auxiliary supply and can deliver up to 0.5 A to AS-I devices connected through its outputs. The 3RK1400-1KG01-0AA1 designation corresponds specifically to the two-input, one-output variant within Siemens’ AS-I Load-Feeder family; the related 1MG01 variant provides four inputs and two outputs for larger I/O needs. Typical applications include powering AS-I sensors and actuators in automated machinery, conveyors, and assembly cells, where a compact, rail- or busbar-mounted load feeder helps simplify wiring and ensures stable 24 V power for the AS-I network.
