Product details

What this AS-i distributor does on the line

The Siemens 3RK1901-1NN00 is an AS-Interface standard distribution board that takes the AS-i flat cable and breaks it out to individual actuator/sensor connections via the insulation-piercing method — no stripping, no separate terminals for the bus line. It handles the distribution function for AS-i flat cables, so the bus power and data run straight through the board to the drop points. Rated for 7 A per contact, it can feed a cluster of small actuators or sensors off one tap without overloading the piercing contacts.

Mounting and environmental range

Ambient temperature range from -25 °C to +85 °C covers unheated outdoor enclosures and hot machine-side locations.

Frequently asked questions

What seals are required for the 3RK1901-1NN00?

When terminating one or both cables in the distribution board, seals for inserting in the bottom of the distribution board are required. These seals are not included and must be ordered separately as Siemens order code 3RK1 902-0AR00.

Is the 3RK1901-1NN00 compatible with standard AS-i flat cable?

Yes — this distributor is designed specifically for AS-i shaped flat cable, using the insulation-piercing method for electrical connection. It handles the distribution function for AS-i flat cables directly.

How do I mount the 3RK1901-1NN00 on a DIN rail?

The IP67 rating requires the screw-mounted top to be properly seated for environmental sealing.
