The Siemens 3RK1901-0EA00 is a power connector set designed as an AS-Interface accessory for load feeder modules. It is a 5-pole, 2.5 mm² version and the set includes one connector and one coupling.
This connector set mates to the load feeder module in the AS-Interface network, carrying the 30 VDC power and data to the downstream actuators and sensors. The 2.5 mm² cross-section handles the current draw of multiple loads on the same segment without excessive voltage drop.
