Product details

The Siemens 3SK2511-2FA10 is a SIRIUS PN interface module — a PROFINET IO gateway for safety relays and I/O blocks in a control panel. It snaps onto a DIN rail (22.5 mm wide, 100 mm tall, 124.5 mm deep) and runs on 24 V DC, drawing 1 W operating power with a 4 A inrush peak at 24 V.

PROFINET IO connectivity

This module speaks PROFINET IO (conformity class B) and supports LLDP and SNMP for network management. It does not carry IRT, MRP, NTP, TCP/IP, HTTPS, PROFIsafe, or PROFIBUS DP — so it is a straightforward IO device for standard cyclic data exchange, not a safety-over-EtherCAT or time-synchronized motion node. The PROFINET interface handles 64-bit input and 64-bit output data.

Snap it onto a DIN rail or screw-mount with the optional push-in lug. Mounting position is any orientation. The spring-cage terminals accept 1x or 2x solid conductors 0.5–1.5 mm² (AWG 20–16 solid or stranded). Shock-rated to 15 g / 11 ms; vibration tested per IEC 60068-2-6 at 0.75 mm displacement over 5–500 Hz.

Frequently asked questions

Does the 3SK2511-2FA10 support PROFIsafe?

No, PROFIsafe protocol is not supported on this interface module. It handles standard PROFINET IO data only.

What is the operating power draw of the 3SK2511-2FA10?

The module draws 1 W operating power, with an inrush current peak of 4 A at 24 V DC.

Where can I buy the 3SK2511-2FA10?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
